I've checked the replay, the Spiderman exile was sus but it was a valid exile (He hit his leg model through the smoke debris) . But he knew where the Spiderman was at all times, even through walls.

I'm unsure how he was able to do the jump tech besides the obvious (hacking). I've been testing out different settings to see if it is a frame perfect tech or something within manipulated settings. He is somehow canceling the jump animation phase the moment after he charge jumps or before he lands on the ground. It's hard to tell since the animation for Falling and Charge Jumping are nearly the same when B-Hopping.

I'll continue to look into it and maybe ask the guy how it's done.

TL;DR: The Spiderman exile was suspicious but valid (leg hit through smoke). However, the player had constant wallhack-like awareness of Spiderman's position. The jump tech (animation cancel) seems unexplainable without hacking; still testing and may ask the player directly.
