I used to have my resistors sorted into four E12 ranges and stored in one 25 bins draw (5x5), each bin had a divider so could take two values.
The 4 ranges were
100R -> 820R
1K -> 8.2K
10K -> 8.2K
100K -> 820K
Plus 2 extra slots for <100R and >1M
So there were (4x12) + 2 = 50 values (2 per bin = 25 bins needed) which is perfect for one 25 draw bin.
Later on i got a massive resistor component stock from someone and their resistors were all E24 so i had to redo the system. I moved it all to E24 and added a new range 10R -> 91R.
So the new system needed (5x24)+2 = 122 values or 61 draws (two 5x5 bins plus a bit of a 3rd bin)
Over the years i added more bins, now i have 11
