I don't think it would be right to penalize a lot of the combinations when the air is that good.
But over a second under in Bristol might be worthy of some horsepower.
The mineshaft rule never took into account the weather.
Ironically, it only came into play when the weather was the worst like Indy.

Great point. I will add - what about the races where Thursday qualifying ends with a "mineshaft bump spot" of -0.80 under. Then on Friday morning, a cold front moves through and now everybody dials 0.20 faster for round 1. So it's not a "mineshaft event" but the immediate conditions are certainly "mineshaft!"

Maybe it doesn't matter because the mineshaft rule is dead but certainly another wrinkle/question mark/downfall/limitation/problem with the AHFS.
