Go in "_Polars" LK8000 Directory and add your polar file.

inside this directory you will found an example of polar, you can duplicate and modify this file.

if you want to contribute to project you can do a "pull-request" on github project toask to include you file in next release.

I'm happy to help with the pull request, I was considering doing exactly this as I fly the same great glider #128578; BTW which polar did you use, what did you base it on? I can't remember how I did, I believe I started from the LX9070 Shark polar. (I have the polar in my lk8000 folder but I did not add it to the official distribution)

@volpe caterina, here is my polar data, before I add it to the default distribution, can you confirm that you are OK with it or that you came up with the same or similar data? (if you ever created it)

* HpH Shark 304 eS 2021-05
* Reference weight: 370 kg/m2
* Max ballast: 194 l (dump time 4 min)
* Wing area: 11.8 m2
370, 194, 80,-0.46, 100,-0.54, 150,-1.21, 11.8
400, 6, 0,L, 79,+2, 85,+1, 95,0, 110,-1, 160,-2

370Kg/M2??? I think you mean 37Kg/m2 right? This is the wing load, not the reference weight..

Could also mean the reference weight of your aircraft is 370Kg then the wing load would be 370/11.8 = 31.14 Kg/m2

I hope you have not flown yet with wing load set to 370kg/m2 in LK8000 as it would generate some weird final glide calculations LOL!
