In this case, I'd like to see empirical data that indicates that bets like 19, 187, etc. ever even occur. I may be a simple tournament player, but in my observation (no data collected) 19 would rarely be used in a T1 tournament - the bettor would just bet 20. 187 - I guess this would also be a T1, and would rarely be anything less than a shove.
The claim a T2000 is more "efficient" because a bet can be made with a single chip is practically ridiculous. The effort used to toss 2 10g chips is the unmeasurably different from the effort to toss a single 10g chip. If you were using 20 lb weight plates for chips, would agree that efficiency matters. For 10g chips, it does not.
