There are some tourneys in MM I used to try to shave a few centiseconds off by swapping buttons, and Teek used to do the same to great effect, so I figured it was a left hander thing

I've never really thought of it for Nono though, that I remember.....hmm....
If two players are tied, then it goes to the sum of the times they have posted (so if someone didn't play a large experty board but made up the points on the other boards, they will probably win easily). And I believe if times are tied to the nearest 0.01, it goes alphabetically.
Check out stephans site at
http://www.stephan-bechtel.de/ for an idea of where you stand: click Nono sites and then in the tournament section, the current season. Looks like you've got about 50 seconds on Vladimir as well as the two points, so unless he somehow beat you by 50 seconds in round 8, you'll win the tiebreaker.
