I’d guess that quite often you’d either win anyway or lose anyway, and that the 20% don’t make the difference. There are so many factors that matter for startup founder success (talent, hard-workingness, network, credentials, luck) that it would be surprising if the competition was often so close that a 20% reduction in working time changes things.
Another way to put this: it seems likely that Facebook would still be worth hundreds of billions of dollars, and Myspace ~$0, had the Facebook founders worked 20% less).
