It depends on what exactly you're looking for in "efficiency'.
When most people peel potatoes they're looking for a time efficiency.
In the one strip method there's a lot of turning the potato going on. And a lot of careful precision. If you've been doing the one strip for enough time you might be close to the million strokes peeling being time effective but for most people...
To be honest I don't really peel potatoes anymore The only dish I would peel them for would be scalloped.
