Heh, heh . . Over the years, I have come to the conclusion that the 60' time is, in drag racing, the most important number you can be concerned with. Granted, ET and Top end RPM are numbers you always want to watch, but the 60' time affects everything after the car's first movement. A consistent 60' time will guarantee you a consistent ET and dial in, generally.
And, it's usually the number that's affected by track condition. Of course, if your 60' time is affected by a hot or greasy track, then of course, your overall ET is affected. This is where suspension tuning and tire pressure is really important.
In Brackets (no secret here), a pure 60' time, and the same 660 ET on each pass will generally guarantee perfect split times at the other end . . And this is true whether you run 4's or 14's . .
