These Sputnik tournaments start with 3min levels and progress to 6, 9, 12 and finally 15min levels. I like long level times, gives plenty of time to play but the last Sputnik tournament begins quite late in the evening and yesterday was the second time I was playing heads-up in this tournament and the HU lasted for 2 hours (it ended at 3.22AM local time for me). I remember the first time the HU lasted for about 2½ hours (this was weeks ago). My suggestion is to reduce the level time on the last stage to 12 so it never progresses to 15min levels so we can all go to sleep earlier. Alternatively add more 9min levels so it takes longer for the game to progress to the slow 12 and 15min levels. Good tournament otherwise, one of my favorites.
