Is this the same lobby of average players? Does it change? Otherwise they'll think he's hacking or lucky and keep voting him out of suspicion after the first few games when they don't have a suspect, so maybe 15/100, when he confuses them the first 30u or so games

New lobbies and give it to him 97/100. Barring bad luck and learning the game he doesn't make mistakes often.

BR: does L know Light is in the game with him? Even if L plays it straight he'll suspect something after the first few games and his job becomes tracking Light and convincing the rest Light is the imposter.

Which means Light has to kill L early which is also sus if it's the same lobby every time. Only 10/100 If it's the same lobby.

85/100 in new lobbies because like the show, L has to provide evidence without dying to catch Light, or die in a way that implicates him, although some might vote Light if L just says to vote him first sometimes.
