I at first grinded using the old PB strats, just to fully squeeze out every last remaining frames I could. I at best got my time down to a 52.80. I then tried the Ledge Grab Skip strat, and while it took a while to figure it out, I eventually got it down.

It wasn't easy, but not that difficult either. I didn't go for the proper swing into ceiling hook setup, as it seems a bit difficult for me right now, so I just do my own slow strat instead, which works out decently. Future improvements will probably require me to go for the full world record strat all the way!
