Agree, and this is exactly why I recently moved away from the "add-on for 1.5x if less than .5x" rule at my game.
For about a year, we did "match half the big stack", and as you can probably guess, that didn't work out well for my less experienced and lesser bankrolled players. So I changed it to the 1.5x add-on and after about a year I can tell that a few of players still aren't that comfortable with how big the game is playing. I've even seen 2 or 3 semi-regs slow in attendance, and then eventually just stop coming altogether.
In hopes of getting those players (and new players) back into the fold I have just recently reduced it back to 1x. We'll see how it goes, first game is next week.
