I'm not saying 1.10 under has to be 3.25% because you are talking about over a tenth with the A/B/C cars but I think a pass of 1.10 under is deserving of 5 horsepower or maybe 1.5% which would be 6 horsepower at 400 or 5 horsepower at 300. Then let a sliding scale do its work.

Instant Triggers
1.10 = 1.5% At 400 = 6 horsepower 300 = 5
1.15 = 2% At 400 = 8 horsepower 300 = 6
1.20 = 3% At 400 = 12 horsepower 300 = 9
1.25 = 4% At 400 = 16 horsepower 300 = 12

Just an idea. Maybe a bad one but hopefully it was spark something to help a failing system.
