I always understood that casinos give-out comp value at 1/3 your expected loss. So there's no way to "minimize EV loss" if you're playing up&up. Now, maybe you can bet big when the pitboss is watching and bet small otherwise, but I was under the impression that casinos are pretty good at guaging how you play.

Note: another way to profit is to be comped things which have a higher value to you than cost to the casino. e.g. A free room on a Wed night doesn't have much marginal cost for the casino, but does have value to you.
