...the only exception being when mafia has a stalker/actress and there are hidden prs such as doc which you want to keep alive. In that case, it may make sense to lynch instead of NL on even numbers, because the chance of prs being alive in late game can be worth the 4 way lylo. But on setups without stalker, always NL on even numbers if maf killed last.
It seems to me that even at the end of that Jan 2.0 game you did not understand why town NL'ed before lynching brown. I would suggest to you to look up what a meteor is. Lynching on even numbers results in 4 way lylo are the end, instead of 3 way lylo. This is why you NL. Myself (and I'm sure a few others) knew that brownpimp was the optimal lynch - however, even if there is autoconfirmed scum, you always NL on even numbers if mafia has meteor, otherwise meteor is passed to the town resulting in a 4way lylo. It may seem weird to NL with confirmed scum, but it's better in the long term by FAR. (ps the only reason why doc died was because he was dumb to hardclaim, instead of claiming 'pr'). So remember, if maf killed last, and it's even numbers of people alive, NL not to get town meteor. (also, you should know that doc needs to no-save on meteor night otherwise it's GT)
look at your wall comments, karma and w/l ratio, maybe it's time to take a step back and consider that possibly you are insanely terrible and try to change your strategy a bit?
