It's been a while grinding, but I finally surpassed JustMog's run. It's not that is was hard per-se, but it's just so "random" to get a landing on the ice at the end. However in one of my runs I managed to skip the ending ledge grab, so it seems if you get enough speed you can jump and land on the ice and then you have enough speed and height to clear the ledge into the finish. So that's what I started doing for times where I got much speed and luckily I clutched it in a run!

It can be improved, I think my first time this skip happened was a failed 49.05 or so. But I don't think it's worth it and most likely just gotta go for the 1st cycle WR strat in future runs.
