Counting Chips Quickly

[ichthyologist]

Last time I had a home ring game, the cashing out took a great deal of time because everyone was really slow (including me) at counting chips, and I later figured out the end result was off by a dollar or so ($5 buy-in game -- so off by a non-trivial amount). Slow counting was also an issue a few times in the game when there were all-in moves.

One thought I had was that stacking the chips in racks (which I didn't have) could help a lot, but all the chip racks I've seen stack chips in columns of 20, which is perhaps too many for useful counting. I was hoping for racks that held 10 chips per column (or even 5), but I haven't found any online. Does anyone know if such racks exist?

If not, are there any other ideas/suggestions about how to speed up the chip counting (other than just experience)?
