Including you slow poke When you have more than 50% of the field going 85 under that means it?s freaking fast out there Mineshaft is more helpful than harmful

Anyway, fair. I can see the importance and necessity of a mineshaft rule. Maybe more generally, when the mineshaft rule isn't/wouldn't be in play, why do we not have AHFS at all of those races too? Like Indy, National opens, etc? Also, what defines mineshaft air and who makes the decision on when the air is too good?

The relationship between AHFS and indexes is out of whack

As you are not allowed to notch pistons for valve clearance, NHRA saw fit to make it illegal to allow your valves to do the job.

Exactly, which is why I asked the clarifying question. If there are that many people with the ability to go 1.0+ under in terrible air, maybe we don't have a mineshaft rule until AHFS has a chance to catch up and get some combos in line.

Sounds good. But, in reality, having the mineshaft rule in place allows less runs to fix your average. Without the mineshaft rule you can fix that 1.00 run on a good weekend. Ask me how I know....

So slow your average at ?slow? races! Mineshaft rules are for extremely fast weather conditions that don?t occur often.
