80% of the time +$12 = 9.6
20% of the time -$8 = -1.6

Net profit of betting $8 on the flop is $8. But when you lead at the flop you are just representing any trips, or any pair.... when you checkraise big, you're representing a very strong hand. You can bet at the flop much more often than you can checkraise it before people start to get suspicious. And in order for the checkraise to get respect, you need to play your legitimate hands the same way. So what happens when you have 82o and you checkraise the flop to $40 and get called? Checkraising risks a lot of money when you're bluffing and makes it hard to get paid off when you're not bluffing. And it inflates the pot size greatly when you're out of position.

And btw, you may think that the big pot bet on that flop looks like an obvious bluff, but the big checkraise looks equally suspicious. Very few players play open trips like that, mostly because the ones that do end up busting out and get replaced by people that don't. For examle, super-aggro overbetter openlimps on the button with J8o, SB folds, BB checks, flop JJ2, super-aggro donk gets all the money in against the ROCK in the BB who has J2s. He had splashed around for 15 minutes building up his manical image and then hit his "big hand" and went broke. Open trips really aren't that great. Am I straying off topic?
