Version 2.1 of Kitejump Beta is released here:

apps.garmin.com/en-US/apps/ca00d0a1-542c-40eb-9ba5-869c8308d865

Changes:


Fixed ( I think ) graph issue in Connect IQ where jump graph data and background were both black ( face palm emoji here )




New user front end screens ( 3 )

Auto session record on application start

Activated calibration menu to increase or decrease detection sensitivity

Added version number in menu for easier feedback



Enjoy and get out there !

Thanks for the feedback...

I really need to see the graph in the Garmin Connect Mobile, so I can see if the 60 meter was a one off or not.

One off's are not currently filtered for until I get my head around how they are being generated.
I can tell you basically they occurs because the watch has detected something that is not a jump, as a jump - and that is where the issue stems from. It could be that you did a jump, and when you landed the watch thought that you had just launched for example.

Do me a favour,
If you are jumping big ) 6 meters plus ), you can try version 2.1
MENU, CALIBRATE ,
Click Decrease detection once..... This will still pickup all jumps from my experience.

However if you are doing small or poor technique jumps ( 2 - 3 metres ) They might be missed

Hi,
Out again today, with updated version. I hadn't changed sensitivity. It's a very choppy and gusty spot.
Says 40m today (although it felt like I was that high I'm assuming I didn't break the world record!). Was on a 7m, gusting 35 ish knots as a guess. I'm not looping.
let me know if you need more pics

Incredibly accurate on the garmin instinct 2 surf edition.

Absolute woo killer. Just gotto work with strava to have a leaderboard implemented and youll completely destroy surfr/woo

What do i need to do to get a lifetime member pass for this watch app dachopper?

Was interesting hearing dave kay talk about it on podcast 365 he stayed fairly neutral but as a bit of a network engineer and flight computer instrument nerd this app paired with the garmin watch and strava possibility is like a drone grenade in a russians trench to the woo
Majority of my jumps were unhooked kiteloops but i threw a few kooky hooked in things just to test the watch for ya

Thanks for that activity summary, that is very interesting !

A - I have no idea how or why Garmin is combining elevation and the kitesurf jump heights together on the 1 graph.
as far as I know it should be two seperate graphs ? My data is the tiny Blue peaks near the bottom - that have been scaled out nearly because of the inaccuracy of the elevation plot. Having said that, reading them looks like a lot of 5 - 6 meter jumps, with 3 0r 4 15 meter jumps, and the 44 meter. I will tighten up the detection requirements in the next iteration.

B - Look at your launch speed for the 44 meter high jump, according to GPS log, you were only doing 7 kts at takeoff, which sounds to me like it's a false jump rather than correctly calculated to 44 meters. ( were you only doing 7 kts? ). The length and hangtime measurements all seem realistic.


Can you open the app, and open the menu ( normal button you hold for menu ), and scroll down to tell me what version that was also?

If no version number in the menu, it's the old version ( 2.0)

Thanks for the picture,

I will change the colour of that graph today, and release version 2.3, the blue is nearly impossible to see against the black in the elevation plot.

Rest of your data looks ok

Did you have a WOO on at the same time?
or
Subjective feeling abouts the highest jump accuracy?

Nah highest jump was spot on my watch was telling me my jump height after every jump and was all completely spot on i have pretty good aerial awareness given my acro flying and freestyle kiteing etc etc im not really into boosting because it tends to pail a little to flying around at 3300 meters so yea not suggesting anything was out of the ordinary with exception of jump length when you do a railey and land hot as a qld summer the distance continues to be read but who cares its at such speed i cant see that being cancelled out unless you filter it with a impact sensor thing but even then i could get around that by just useing my body to take the shock and wouldnt trigger it.

So what do you think about going the strava route for leaderboards useing theyre segment/route mapping? Or maybe a upload file style ala www.xcontest.org/world/en/ that we do for paragliding flights? Or we could go toplogger style works great for climbing gyms around the world www.toplogger.nu/en-au/home makes climbing in a non top logger gym seem like a waste of time
I use all these pretty much daily and happy to send ya some screenshots of them small explanation how they work etc get ya in contact with theyre developers etc

Thanks for the feedback

Yeah, I have interest from several at the moment, some on IOS, some on android, and some HTML.
With the Garmin ecosystem, I can get GCM, to tell your phone ( android or IOS ), to open a webpage that I have uploaded data to, so a web interface probably sounds like the best option here, but I'm looking into others like ZEF and waterspeed as they can import the data, or I can upload to them.

My priorities right now though are fine tuning the GCM displayed data, the jump triggers, the filters, and the assumptions.
Need a couple of months to get more data on the assumptions, as all my testing has been relatively small ( 4 to 10ish ) meter jumps so far.



VERSION 2.3 released now
Jump Graph now white on black
Detection threshold increased to avoid false jump detection
Min jump speed increase ( 8 kts ) to avoid false jump detection
calibration menu re-worded.

10 x face palm emoji's !

Some users have black background, some have white.
Colour changed to electric green on white or green on black.
Graph will show peak heights, and change when another peak height is registered.

Version 2.4 now released

If i use it while paragliding will that screw all ya data or do we have to manually send you the data?

Some body is scared of you

Funny how they neglect to mention garmins barometer which all flight computers use




Oh unrelated i logged out of my paragliding setting on instinct surf 2 and logged into your app mid flight and it kinda acted a little different obviously didnt register any jumps etc cause i was flying pretty smoothly on coast will try again starting with it on prior to launching.

Version 2.6 released.

2.5 was compiled in test mode by mistake, meaning 6.4 meter jumps for everyone.
Please delete version 2.5 and download the latest ( 2.6 ), which I've tested and is now live...... Unless you want a million 6.4 meter jumps in your jump graph
