Interesting. Reminds me of a positive progression and makes me think of playing it with Sputnik's Regression Up & Pull:
2,1,2,3,4,5,6,7,8,9,10... etc
Where we stay at 2 units until a win and then drop to 1 unit and proceed through the progression steps as long as we are winning. Otherwise we drop back down to 2 units, starting over.
