Player responsibility to correct minor(?) dealer error?

[EWillers]

I play a lot of NL live. I have a system for making bets. When the bet I want to make is less than 16 chips, I go ahead and cut out the exact number of checks I bet.

When the bet I want to make is between 16 and 25 chips (25 is a maximum handful for me) I simply grab about how many I want to bet overhand and put them into the pot. I figure I'm not gonna be more than 2 or 3 chips off and it's not that big of a deal.

When I want to bet more than 25 chips I slide the stack(s) into the pot. Again, I feel I only need to be within a few inches of how much I want to bet.

The potential problem arises in the middle (16-25 chip) category. When I put out what feels like 22 or 23 chips or so sometimes the dealer will just assume it's 20 chips and announce $100 (or whatever 20 chips would constitue). In a $5 or $10 chip game this isn't a huge deal (though many, not entirely basslessly, would argue it's not always insignificant). I hope to play in bigger games at some point.

When a dealer mis-announces my bet like this, is it my obligation to correct him prior to other players acting?

In anticipation of questions about why I bet like this, I have two reasons.

1) (and the dominant reason) Reading Navarro, I became really paranoid about my motions at the table. I see this as an extention of "robotic" play. I don't want to be fumbling around trying to create 20 chips stack(s) and cutting lots of checks into the pot. Also, if my opponent asks how much the bet is, I pretty much force him to speak.

2) I actually see this as having a net effect of being faster than the alternative. Frequently, the larger bets are never called or even contemplated. The time I don't spend trying to come up with, say, 55 chips or somethin' is greater than the time spent when they do ask how much that is and the dealer has to count it down.
