what is the relationship between your 60' time and your final ET? Is it 1 to 1, as in if you lower your 60' by 1 tenth your ET will be 1 tenth lower too? Or does a .1 decrease in 60' take more than that off at the other end?

 

.1 *can* equal a little more at the traps. Every tenth to .05 helps at the end. My best 60' times on F1s at 1.8x netted some nice mid to upper 12s. Mid 1.9s to 2.0x barely let me touch 12s.

 

im probably wrong but i always get the idea that for every .1 better on 60ft gets you at least .2 on your final E.T

i ran 13.5's w/ a 2.0 60ft

i ran 13.0-13.1's w/ a 1.8 60ft.

and i run in between that when i am 1.9 60ft...

that is the difference, it's all in the 60ft.

 

You are correct Cobra Snake .1=.2

 

yep what they said
1 tenth off the 60= 2/10th's better ET (give or take a hair)
