I know a lot of players swear by this rule or strategy. I don't. And while I can's say for sure it has never hurt me, I am doing pretty well longevity wise.
If you watch other (non card counter) players, it isn't unusual for a player to place a higher wager after a loss, trying to re-coup that loss plus some. It is a form of chasing actually. Now I am talking modest increase (if the count calls for it), not minimum wager to max bet. I also don't think it even looks that unnatural. Once the bet is lost and chips collected, you have to go to chips anyway. If someone is going to notice that you now wagered 6 or 8 green chips, when your last wager, that has already been collected was 4 green chips, you might have a problem anyway (like already being evaluated). But I just don't think this triggers anything since you HAVE to go to chips anyway for next wager. Just my opinion.
I do adhere to the only increase from chips in the circle after a win rule. That would be your original bet plus winning, which will only allow you to double unless you win a BJ, double down or split. It looks very unnatural to win a wager and increase more than that win (going for additional chips). So the down side is if the count suddenly rises dramatically, it may take you 2 rounds to catch up.
