1001 Spikes level 10-4: Tricky jump strategy

Solution 1:

I've actually been struggling with this level a moment ago, which quickly went from "this puzzley level is my favorite in the game" to "this is the worst level ever". But I digress.

I haven't had the time to develop muscle memory for this jump because I got lucky, but the few attempts when I had an actual strategy I had most luck with this setup:

The left foot should be standing almost exactly one tile away from the spikes.

Please note that the actual screen is from a different location in the same stage, but the idea stays the same. It might also be that you have to be one pixel to the right, I am not 100% certain if I am pressing the two keys at the same frame.
