First of all you are in the right direction that you working with a plan. Your plan is not the best for the long run because of the ratio but I am sure you can tweak it.
8 wins in a row is great but don't carry a way. I had once 20 wins in a row and then came one big loss that wiped everything. And have you thought how you will handle 5 losses strike? or 8? or 10?
