I'd be suprised if Maria's bands and percentages fitted what you were trying to do anyway as I mention above.

The power of banded staking in my opinion is the ability to ignore bands. As an example with the selections I've been testing this on all my laying profit comes from the bands

2.00 to 3.15
6.60 to 7.60
17.00 to 25.00

The gaps particularly 7.8 to 16.00 are big lay losers.
