I was finally able to fix this super annoying fly false positive while towering up. Many people have reported it, but I've been struggling to find the cause for it for a while. The problem was that floating point accuracy changes with different number scales, so the false positives only happened at certain heights.

The config file wasn't changed

Changelog v0.14.3:
- finally fixed a super annoying and elusive false positive while towering up (the problem was related to floating point precision changing with different exponents)
- fixed a packetspoof false positive when walking on a shulker
- fixed a fastladder false positive when climbing a ladder while having a levitation effect
- fixed a speed false positive when using a trident with riptide
- removed "No Fall" from the packet spoof check because this check can get triggered by many other things too
- removed some old code which isn't necessary anymore
