The day’s wind, hour by hour and leg by leg

Measured in kilometres per hour · no expected direction

What the air did, read from the field itself. We estimate the wind from the circling of every pilot. The first method is the drift of the circle centre, and the second method, used when the first is not available, is the modulation of the ground speed. We then combine the estimates two ways. The table by hour of day shows how the wind increased and changed direction through the day. The table by speed-section leg shows the wind on each part of the course. This metric describes the day, so it has no value for each pilot.

16:00 AEDT	10.0	321	1663
17:00 AEDT	6.8	55	560
18:00 AEDT	7.1	80	30

Each circle gives one wind estimate. GlideComp uses centre drift where it can, and ground-speed modulation where it cannot. The direction is the vector mean of the estimates, in degrees the wind blows FROM (0° = north). The speed is the median of their magnitudes, because the length of a vector mean falls toward zero when the directions scatter.

Hours are shown in the competition’s time zone.

“Flown” is when the field was ON the leg — the first pilot entering to the last leaving — over the “Pilots” who started and flew the whole leg.

“Circling” is the narrower window the wind was actually measured in: first to last circle estimate any pilot logged while on the leg, from “From pilots” pilots. Glides produce no estimate, so a leg the field mostly glided shows a sliver of its flown window (or “—” where no one circled at all) — and a late leg the leaders glided can be measured EARLIER than the leg before it without either being wrong.

How strong the day’s climbs were, hour by hour

Measured in metres per second · no expected direction

When the day started, reached its peak, and ended. We group the thermal climbs of all pilots by the hour in which each climb started, labelled in the time zone of the competition. The median and the 90th-percentile average climb rate for each hour show how the lift developed. The first row is the whole task, measured over every climb of the day in one set, and not as an average of the hourly rows. This metric describes the day, so it has no value for each pilot.

Climb by hour

Period	Median (m/s)	p90 (m/s)	n
Whole task	1.1	2.1	1209
13:00 AEDT	1.4	2.3	6

16:00 AEDT	0.9	1.9	358
17:00 AEDT	0.8	1.1	107

The average climb rate of every thermal use across the field, grouped by the start of the climb. The hours are in the time zone of the competition. The whole-task row is measured over all of those climbs together, not averaged from the hours.

Share of the flight spent in air that wasn’t sinking

Measured in percent · no expected direction

How much of the flight was in air worth being in. The value is the share of the airborne time of a pilot, on the shared grid, with a 30 s-smoothed vario at or above −0.5 m/s. The time they flew, the line they steered and the way the flight ended all feed this value. It is therefore a reading of the day as much as of the pilot. There is no expected direction, and the sign of the correlation is the finding. The timing table compares the window of the day’s best climbs against the time when the field launched.

Day timing

	Time
Best conditions	14:00–15:00 AEDT
Earliest takeoff	13:42 AEDT
Median takeoff	14:44 AEDT
Latest takeoff	15:23 AEDT

Best conditions is the one-hour window with the strongest median climb (1.5 m/s), among hours with enough climbs to be representative (≥20% of the busiest hour).

Share of lift turned in that was kept as a climb

Measured in percent · no expected direction

How selective the pilot is about the lift they stop for. Each period of circling of 30 s or more after the start counts as lift that the pilot sampled. If the period overlaps a detected thermal, the pilot kept that lift. If it does not, they turned a few circles and left it. The value is the percentage kept. A low value means they are selective. A high value means they keep almost every climb they turn in. There is no expected direction: selection wins on a strong day and wastes time on a weak one.

Median per-pilot acceptance %, bucketed by the hour (competition time zone).

How round and consistent the circles were

Measured in ratio · no expected direction

Whether the pilot flies clean, repeatable circles, or moves around the thermal. We fit each detected circle by least squares. The RMS fit error divided by the fitted radius measures how round the turn was. The value is the median over all of the circles of the pilot. A lower value means smoother and more consistent turns. There is no expected direction: a rough trace can be a pilot chasing a drifting or broken core rather than a pilot circling badly.

Turn direction across the field: 82% left (5519 circles).

Glide speed between climbs

Measured in kilometres per hour · higher is better

How fast the pilot moves down the course when they are on a glide. The value is the duration-weighted mean ground speed over every glide after the start, which is the glide distance divided by the glide time. A higher value means more ground covered in each minute between climbs.

Field glide speed: median 58.3 km/h · p90 69.5 km/h (36 pilots)

Share of race time spent hunting for the next climb

Measured in percent · lower is better

Time that goes into neither a climb nor progress down the course. This is the time spent to find lift, to stay up, and to decide what to do next. The value is the share of the speed-section time, from the start to ESS or to the landing, in which the pilot neither climbed in a thermal nor glided with real net speed. A lower value means less time lost between climbs.

Speed-section phase shares, field p25/median/p75: climb 29/32/35% · glide 24/29/33% · search 32/39/46%

Time spent flying with a gaggle

Measured in percent · no expected direction

Whether the pilot raced with other pilots or alone. The value is the share of their flying time after the start inside a detected gaggle, that is, clustered with one other racing pilot or more on the shared time grid. There is no expected direction. A gaggle increases the power to search for lift, but it also holds a pilot to its own speed. The sign of the correlation says which of the two occurred here.

54 gaggle episodes detected (peak size 13 pilots).

How long after the gate opened the pilot started

Measured in seconds · lower is better

Every second between the opening of the gate and the crossing of the start line is a second lost for nothing. The value is the seconds from the start gate taken to the scored SSS crossing. On an elapsed-time task, the pilot’s own crossing is the reference, so the delay is 0 by definition. The start table adds the crossing altitude, and the distance behind the leading pilot who had already started.

Delay = gate taken → SSS crossing. Behind km = extra distance to the next turnpoint vs the furthest-along already-started pilot at the moment of this start (time grid).

Race time lost against the fastest pilots, leg by leg

Measured in seconds · lower is better

For each completed speed-section leg, we compare the leg time of the pilot with the mean of the top 10 pilots by rank who completed that leg. Only the losses count, and we add them together. The sum of the leg times is the race time, and the rank defines the reference, so this metric follows the result by construction. Read the waterfall table, which shows every leg against the task winner, for the diagnosis. Do not read the correlation as a finding.

Jon Durand, over 5 compared legs: +48:33 overall. — marks a leg the pilot or the winner did not complete; the table below has every pilot.

Each cell is the leg time of this pilot minus the leg time of the winner. A + value is slower than the winner, and a − value is faster. A — means that the pilot or the winner did not complete the leg.

The scalar metric instead adds the losses against the mean of the top 10 pilots who completed each leg. A leg flown faster than that reference contributes 0.

Race time behind the leader at ESS

Measured in minutes · lower is better

At each speed-section turnpoint, we compare the elapsed race time of the pilot, which is the reaching time minus their own start, with the fastest pilot to that turnpoint. The value is the minutes behind at ESS. It follows the final rank almost exactly, because this metric is the sanity check of the evaluation.

A line that stops early is a pilot who landed. The top 5 are coloured; the table below has every pilot.

The elapsed race time, from the pilot’s own start, minus the fastest elapsed time to that turnpoint. A — means that the pilot did not reach the turnpoint.

Arriving at ESS with height to spare

Measured in metres · lower is better

Height still available at ESS that the pilot no longer needed. That altitude was available for more speed, and the pilot did not use it. The value is the altitude at ESS minus the altitude needed to glide to goal at the standard glide ratio of the sport, which is 5.0 for HG and 4.0 for PG (S7F §13.4.6). A large positive margin means the pilot arrived too high. A margin near zero means they flew the final glide with little height to spare.

ESS altitude margin over final glide: top-10 median 393 m (n=1).
