Thx for supplying the math scrote, saves me firing up pokerstove
I'm sure Stu is just pulling one giant level, although he's tight (and scottish, coincidence?) i've never seen him blind down that much in a non LPL game. I reckon he's sucking you in so that in a meetup game everyone respects his shoves.
Judi one more thing I would add is that i've been known to shove blind with a c.10bb stack in late position , of course not letting others know this by feigning a look, or if you want to get sneaky just looking at one and shoving, obv repping an ace. There is an obvious downside to this but the advantages are: opponents can not read if you're strong or weak as you do not know yourself!, you push with hands you'd muck (rightly of wrongly) and also you don't try to get cute with a big hand.
Another thing I'd add is that the threshold for shoving ATC is higher in MTTs than in sit and gos, purely due to the flatter payouts and shallower stacks in sit and gos than in tournaments. Often is sit and gos you still have fold equity with five big blinds.
