after some testing and using of the bins, i ran into the problem that making equal steps from 0 to 2.147.483.647 in 4 tiers is do able:
Tier 1 8.192
Tier 2 524.288
Tier 3 33.554.432
Tier 4 2.147.483.647

(How did i do it:i add 1 to the max int and divide the result by 64 each step)
as you see the steps are enourmous, which is in my eyes a problem.

so i thought about that it will be better to have more tiers to have closer steps
and a diffrent tought was to have only one tier of storage with max int value.

This is why the configuration exists, so that you can change the values to your liking. Current values are scaled to the way I intended.
