Metric Info:
Track: The GPS track (every fix) in a glide between 2 thermals Including Thermal Attempts
T-Track: The GPS track (every fix) in a glide between 2 thermals Excluding Thermal Attempts (this is a better metric to use)
Glide: The distance or time between Turnpoints Including Thermal Attempts
T-Glide: The distance or time between Turnpoints Excluding Thermal Attempts
Task: The assigned task
Race: The achieved distance or time for the assigned task
Stab: Stab or Stabilised is used in thermal averages excluding the 1st and last orbits
ttrack Netto: The netto
Thermal Lost: The altitude lost between fixes while in a thermal (slow to center, stay too long)
Tries Lost: The altitude lost between fixes while in a thermal attempt (slow to center, stay too long)
Orbit Time: The time to complete an orbit.
Orbit Speed: the Ground speed of an orbit.

Notes:
- All speeds are Ground Speed, wind is not taken in account.
- A Try or Thermal Attempt is counted if the glider circles of over 18 seconds but under 60 seconds.
- A thermal is counted when the glider circles for over 60 seconds.
- Use of a logger with GNSS (GPS) altitude instead of pressure altitude will have far less reliable statistics.
- Polar and wingloading are critical for netto and speed to fly calculations, invalid entries will give eronous statistics.
- Netto is calculated for each segment (fix) rather than for each glide.
- Leg STF is based on the next thermal climb rate and current Leg netto. (Previous climb for final glide)
- For Events loaded prior to Aug 2024 Times are UTC, for after Aug 2024 times are local event location.
- Events loaded from July 2024 till 11 Aug 2024 have incorrect Netto and speed to fly.
