[Stumpy]

(It is +$EV to shove. ~$350 - $400.)

MUD, you can pretty much say 1 chip = (Prize Pool) / (Chips), with Adanthar's numbers 1 chip = $0.0625.

The difference between 10th and 9th is 12,800 chips.
So when you go all in and are called, add an additional -12,800 to your stack as a loss.

Blinds and Antes are 12,000.

F = Everyone Folds.
W = Win Chance if Called.

$0.0625(12,000(F) + (1-F)*(66,000*(W) - (66,800)*(1-W))) = Profit from shoving.

I'm ignoring when SB and BB both call, and calculating W as a weighted average of the two calling ranges.

33 vs Top 5% = 33/67
33 vs Top 10% = 40/60
33 vs Top 20% = 45/55

The more they call the worse it gets, but it never goes negative.
Even if they both called top 20% hands, (or Big stack called 30% small 10%) you're still +$321 by shoving.
For more reasonable 20%/10% calling ranges you're +$378
