Hi mpichler.dev,

That is an interesting method for sure. If you're able to place your fingers down from ring > middle > index, and you're able to achieve 1 finger per fret that way, it should work the other way around as well.

It sounds like the problem is not your inability to stretch your fingers for each fret, but more of a muscle mechanics thing. I suggest practicing spider legs so you get a good feel for moving your fingers forward and backward, from index > middle > ring and then reversing it.
