Happy New Year! 
I know it's hard to get load enough games at night, but still, I'd rather play 1 less table, with more focus, than include a 9-man into an MTSnG session, except if I loaded it at the start of a calendar hour. You should have a rest during synchronised breaks, and it's spoiled if you have to act at that 9-man table.
Besides, there are disappointingly many high volume 'regs' in the $0.50 9-mans, so I've given up on them - 18-90 mans are noticeably softer (I don't like 180-mans because the bubble is lighter there, and opponents' ICM mistakes cost them less money). Feel free to disprove me - I know that a lot of people simply don't care about their tiny buy-in in the $0.50 9-mans and 'throw free chips at us', but there are plenty of reckless gamblers in MTSnGs too

100 buy-ins for MTTs is a super loose bankroll management. 300 buy-ins should be standard for 180-man sngs.
25 buy-ins for NL2 is a standard BRM. You should not have 10-20+ downswings on NL2 because the games are not aggressive and everyone there plays terrible.
The BRM always depends on the relative skill. $15 on-demand turbos require an average reg to have a $3K+ bankroll because the opponents are tough on average. The 300 BI figure likely comes from the pre-2016 era when regs were loading a ton of midstake games to earn as many VPPs as they could.
There's no need for such caution at the micros. At the lowest level - $0.50 turbo 180-mans - a $30 starting BR is enough for a competent reg, especially because there's an option to move down to $0.25 non-turbo 45-90-mans every time when it falls below $10.
To each their own - I'm bad at postflop play, especially with 2 hole cards, and probably wouldn't last long at NL2 if I were given $50 to play it
Fortunately, at MTSnGs, it's not as bad to sit tight for the first few blind levels while opponents increase my equity in the prize pool by busting each other.
