wow, this was way more polarizing than I thought when I was the first reply to this thread.
I was all for just using exact times always (well, as exact as replays allow) in all games, 2v2 and 1v1, but as we can see 8 pages later, many are vocal for keeping ties, (at least for 1v1 mainly).
So I'll adjust my stance: all 1v1 stays the same except when both players agree to use exact times before starting. This seems fair, as there's definitely many who still like playing again after ties (or just don't want to check), and it allows the chance for two people who like exact times to meet.
as for 2v2, I feel the opposite should happen, due to the obvious flaw of a team being 1.96 slower yet still winning. We let this slide in 1v1 because it's only ever a maximum of 0.98 between two players with a possible tie. In 2v2, there's no excuse to let this increase to 1.96 where not only does it introduce possible ties, it also introduces possible slower teams winning when they should 'tie' or even LOSE. all 2v2 should use exact times except when both clans agree to use whole seconds before starting.
