First sub 3 IGT?

I think my timer displays IGT instead of RTA, 3:47 RTA that means second place, with IGT wr. I wanted to get a better run but I'm consistently losing 5 seconds at the start in runs that look the exact same, not sure if it is screen transitions, if jumping loses time, grabbing the ledges earlier or late, I tried everything but I cant find why im loosing time xd

So this is my pb for now

mod edit: re-timed to 3:46.067
