First 50 usually because I usually start fights before then. And I generally try to get to SD by or during the endgame. Sometimes the latter backfires if there’s some nasty aji in a corner and I die.
I think I get into byo-yomi some time in the early 100s.
But my opponent usually has at least five minutes left on their clock. I don’t really understand why people take 10+5x30s to show off how good at blitz they are.
I can’t actually remember the last time I wasn’t the first into overtime.
