Yep, it's a pain.
In my stumblings with this method so far, it becomes a tradeoff of camo vs betting optimalness.
Full-discipline would have you continue to only parlay 2x of whatever the winning bet was. And if you have a split/doubledown situation, this means only the original bet.
Somewhere (either Blackjack Attack or some QFIT sims, I think) I saw some math that the optimalness of the betting is hurt most in single-deck games, where the count changes the fastest and the shufle comes soonest. It's hurt least in shoe games, where the changes are usually more gradual and you get more hands in. (In hurts very little in shoe games)
From personal experience, I can vouch for this effect when last time I played a SD game (at El Cortez, teehee). I was religious about only parlaying on wins, and I kept my bet the same after the shuffle. Instead of having any defineable "ramp", my average bets just ended up "wandering" during the course of several shuffles, from fairly low to fairly high, and back and forth. It was kind of strange, and it was either great cover, or horrible playing. Probably the latter.
Now, if you want to break from full parlay discipline, you can chip away at the edges. Maybe increase bets on losses as well as win. Maybe "super-parlay" winning doubles/splits. It's the art of The Act, which I'm weak at.
Also, if you're playing two hands, you can get into some more unusal combinations. I kind of enjoy playing two hands of dissimilar size once in a while, but when I do it, I'm only guessing at the optimalness of the bets from an EV and risk standpoint. (I just try to ensure that the bigger bet is not as large as my one-hand bet would be for that count, and that the aggregate bet is more than the one-hand bet, but never more than the aggregate two-hand bet would be).
