(20-49) is not ideal, of course. I couldn't come up with anything better.
During the game, every second counts – it’s unrealistic to look at a bunch of different banks and calculate how many are in one stack and how many in terms of the game. But this is more or less okay…

That’s what I was saying too. It’s difficult to quickly grasp a lot of values like (20-49); something more convenient for perception is needed. I don’t have an idea yet (other problems). Perhaps another approach to the table (not horizontally, but vertically), or basing it on other parameters...
Yes, also check out this post /topic/at/495367/ and review the subsequent ones up to 499 – to adjust another section. That should be all.
Try writing it like this: 10 (50+ or 10+GS and 20+) in one line, without highlighting a separate line for GS.
