I run my mechanical set up pretty tight, with the TO "all but touching". Yeah adjustments are more frequent in terms of mileage driven, but it still lasts pretty much all summer.
That 1inch freeplay slows me down too much,lol.
That's ok as long as you don't have some kind of lever that has counterweight. Well, all fingers or levers are subject to centrifugal force, but I know my fingers have about .060-080 movement. So I give myself about .100 and don't ride the clutch like a sissy!
If you ride the clutch pedal, you have to have more free play.
