1/8 Mile Index Question
 
Class 1/4 Mile 1/8 Mile
AA/S 10.00 06.50
SS/JA 11.00 07.10
G/SA 12.00 07.68


Using these three classes as examples,how did they come up with the indexes at the Gainesville Divisional in the 10.0,11.0, and 12.0 indexes classes on the 1/8 mile???

They had 10.00 @ 6.40
11.00 @ 7.00
12.00 @ 7.50

Re: 1/8 Mile Index Question
 
Apples and oranges; the index classes are same as the "unleashed" format and their 1/8 mile indexes are in line with SG and S/ST indexes. In fact many of the local tracks that run heads up classes on the 1/8 mile use those same indexes.

Our indexes have never been in line with heads up classes of any kind...besides the stock indexes don't even come into play in races unless you're running a CIC program.

Re: 1/8 Mile Index Question
 
A formula that I have used to convert 1/8 mile times to quarter mile times........1/8 et X 1.58 equals 1/4 et...........
