Default Ahfs???

I've read and reread nhra's post about the ahfs.
I understand the trigger for an instant hit is 1.20 under
I understand that the trigger for a review is 1.00.
What I don't understand is the fact that they say if your class/engine/combo average is more than .85 under it warrants a hit. But their data starts at 1.00 under
I've looked at this for a while now. And it looks to me like if your class/engine/combo average is between .85 and 1.099, under you get the hit for 1.00 to 1.099 under.
Is this correct?

It is ambigious in the NHRA description but, In the past the fastest trigger run decides what the % increase is.

1) There has to be two triggers to warrant review. for example one trigger of -1.080 & one of -1.111


2) If the engine family average or class average is faster than .-850, than the combination recieves a hp hit.

3) The precentage of hit or amount of index is determine by fastest trigger. In the example I gave a hit of 2.25%(-10 of index) would be given because of the faster triggering run being between -1.100 &-1.199 under if the average was faster than -.850 under.

Okay. Thanks
So the .85 average is the deciding factor. If you make 2 runs over 1 second under.
