Expected Behavior

Crushed Ore -> Impure Dust lists the chance for the chanced extra dust as 14% + 8.5%/tier. At HV the odds in EMI are listed at 31% and at UV, 73.5%, which matches what is expected. So macerating 64 crushed ore should result in an average of 19.84 extra dust at HV and 47.04 at UV.

Actual Behavior

However, actually testing it I saw only 13 and 14 in a few tests at HV, and at UV I did a lot more tests and saw only 41,42,43 (and only a single 43, the vast majority were 41/42). The numbers suggest that it may be one tier of bonus missing (the chance in EMI is not counting ULV as a tier, so it's not that the chance is reported too high from that).

Steps to Reproduce

Creative, place UV macerator + infinite energy, configure energy to UV and activate, put a stack of crushed iron ore or whatever in, and see around 42 nickel dust. Repeat several times to confirm that it's not just luck (though I see in the code it's supposed to be mostly deterministic).
