Doing no inventory here loses about 0.4 to the thing people normally do here (inventory asap + landing at the bottom before the transition).
For reference, being too far right on the inventory open having to open inventory again loses at least 0.6, landing on the ledge loses about 0.8, and being too far left and dunking loses about 3s. So I think this is a nice middle ground that loses a little bit less than messing up the other strat and is much easier to hit consistently.
Slight modification to this strat that loses another 0.1s or so but also avoids most of the bad patterns with the second to last petra. I'm using the background vines in the screenshot as a cue for when to dash. Still not an ideal strat but worth messing around with I think.
EDIT: I've realized you can decide which strat to do on reaction. As you dash to the first collapsible platform, take note of the petra's position. If it's very high and to the left, or directly in your jump arc, do this safer strat. Otherwise the original should work fine.
