How many passes does a driver need to make...
 

...on a certain Stock combo at a divisional or national event before they can request a h.p. adjustment ? ( i.e. reduction)

I have read and re-read the section in the AHFS section and am familiar with the time windows one must run to qualify for an adjustment.

Just never saw anywhere where it said how many runs would have to be made within those time windows.

1 run ?
2 runs ?
3 runs or more ?

Anyone know how many runs need to be made ?

You need to PM Charley Downing, he has proclaimed to be the expert on the AHFS.He claims to have taught Larry Hill how to work the system. I know for a fact that one race will work if your combo meets NHRA's criteria.
