Not by me though... Some ideas here and there especially from Punisher and Pitracer.

It gives a better punch on the clutch. The clutch does not seem to slip. With a .4 mm end float, you bring the clutch shoe closer so that you can tighten up the clutch spring and still get the clutch to engage.

The end result is you get a very punchy and responsive clutch and because of the smaller end float, you get a smoother clutch engagement which can be almost instant depending on how you set it.
