Suited stuff, enough odds? 40 at the Borg

The issue isn't percentage, or at least not here. The issue is that you're paying 3 bets to get into the pot, which means your investment be paid off 3 times what it would normally be compared to a pot in which you limped in.
(ie. The return on a $1 investment that has a 10% chance of success needs to be at least $10 to be break even but the return on a $3 with a 10% chance of success needs to be $30. )
Given the way poker works, your initial investment is only thinly correlated with how much you can expect to make postflop. If your hand was hit 20% the time, (rounded for simplicity) you would need to make 5 SB if you limped, a reasonable proposition. However, you would need to make 15SB if you coldcalled 3 bets, something that is much harder to do. This example eliminates paying bets postflop when you chase your draws for simplicity, but the point stands.
