Awesome run!
I made a few discoveries that you might want to incorporate into your run! I am not good enough to beat WR myself (yet) – or at least I think so! ;)
You can see my run with the implemented strats under the ghost "strats on lap"
1. If you take the right loop at the start, you come out of the loop up to the second cp considerably faster (240 speed vs. 190 on your run).
2. If you do a small brake tap before the jump up to the third cp, you will carry considerably more speed, bc. of reduced air time.
3. Get an end jump as incredible as yours and no one will be able to beat your record ;)
Looking forward to seeing your run!
