Also i must say i have the woo and got one time on the woo jumps recorded at 28m in 15 kts.... I'm almost sure than half of the top 30 leaderboard is due to some measuring issue.

Do you plan to integrate some algo to detect such thing and prevent such fake leaderboard ?

The woo sometimes measures incorrect values due to incorrect landing. You will also see very low G and very long hangtime.
No problem because you can remove an incorrectly measured jump. This does not mean that the whole leaderboard is incorrect.

OK, let's take one thing at a time. First of all, the 28m jump. Did you see it on the watch in Woo Screen app? If yes, was it still present in your session when you loaded session from your WOO to a phone? Sometimes WOO does report erroneous jumps, but most of the time they are filtered out by the official Woo app during loading. WOO gave me some of the filtering algorithms they use, I might implement them in the Woo Screen app later on. So far it wasn't much of a problem - I myself saw it only once.

Second, if the 28m erroneous jump did get loaded and posted on leaderboard. A lot of us self police and delete such jumps. They are easy to spot, just look at the other jumps in the session, and also history of previous sessions. People who can really jump high tend to do it often :D . By now we know most of the people on Woo leaderboard by name, just because we see them on daily and weekly leaderboards all the time. If a new name pops up, I usually go through his/her history to make sure it is not a one time luck or error.

And lastly, you asked if I (a developer of Woo Screen app) can prevent erroneous jumps from polluting leaderboard. The answer is no, it is not possible for me to do it. WOO sessions and leaderboard are maintained by official WOO app, my app just displays jump height reported by WOO in real time :) . It does not save it anywhere - that is what official WOO app does.

You should. If not for yourself then for the rest of us, so we can measure up to you :D . There is an Airstyle too, would be nice to see you on its leaderboard :thumb:

Aleks, does watch record gps track? How can I get it out from there, at mobile app I did not quickly find download option.

If watch does not record track/gpx just write gpx xml in ring buffer and every flash sector (512 bytes?) write to flash. When mobile phone is connected and non-pushed file is on watch do a bluetooth push or something to upload track.

Sorry, the track is not supported yet. At the moment I can't promise any track related development :(

I see season is on for you.. :) Awesome jumps at Woo boards on your account, became a "woo-friend" today.. Jumping with hydrofoil and 10m foil kite (Elf)? What kind of winds for 22 woo-m jump on that setup?

But I'd emphasize that after-session-GPX-analysis even more important to do on lift-off speeds, directions and resulted jumps etc to check areas of self-progress..
