I still had the original clutch in my Civic when I traded it at 200,000 miles. That last third of that included HEAVY use of bump-starting, multiple times per mile.

The longer you can glide the better your results. The magic of P&G happens in the glide, not so much the pulse. So you want to design your cycle to have long glides. Then, the question of "how short to EOC?" isn't so much of an issue. That being said, my cutoff is somewhere in the 5-10 second range. Not worth the key-off-bump-start cycle for something so quick.
