Seems easier to me to say they are logarithmically distributed, rounded to 2 digits. Like yes, this means that if your manufacturing tolerances are typically some percentage of the amount (more natural than an additive error) then the overlaps are nicely spaced. But a log scale means that's true for any relative allowance (manufacturing or otherwise), which is the much more natural sort. It doesn't matter if your 100-foot house is off by 1mm, but it does matter if your 1mm-thickness fork is. |

Except that it is the tolerance overlap that allows for that specific distribution to work.
