The best way i can think of to understand how you are betting, is to show your actual sequence of a day or 2 betting activities.

For example.

BET 1. Odds. Bet Units. Win yes/no, if win what did it pay, return.
BET 2. ,,.......... etc.

From then on i am sure some form of a basic architecture may fruit.

Other things you may include is betting bank size. That way if you are on a looking streak, the sums and excel formula can be implemented to.
It's basic bookkeeping.
