M 10
L 30
XL, Jebus 60
+6+1?
P.S. 10 for M doesn't really matter anymore, it's just to make the number round for aesthetic purposes. :)
Well, as someone who has played Jebus 4000+400, I understand that I'm not the only one who will surpass this, especially considering this timer (I'm not even going to play on it), but the idea of fixing +6+1 actually looks pretty good.
