Attempted this for over 10h and was able to finish only 6 attempts: 40.56, 40.43, 40.96, 40.56 and 41.00.

I gave up, but came back somewhen else. After some practice I started attempts and choked the last jump after just 1 min of attempts. Just 2 min later I ended up getting this. Also the attempt I choked was on the exact same pace as this one.
