That may be your issue. I believe EQ utilizes
floor(x) instead of
round(x), or whatever the EQ equivalent is of those 2 matlab functions.
Examples to help make things clear:
floor(32) = round(32) = 32
floor(32.3) = round(32.3) = 32
floor(32.5) = 32, round(23.5) = 33
floor(32.8) = 32, round(32.8) = 33
Basically, until the new integer number is actually obtained through mods/levels, the next lowest is used. You can never "gain" values (damage, healing, +resist) through rounding, but you can "lose" some through the floor conversion (always <1 value lost).
Graphically, it would look like this, with the solid circles indicating inclusive on the lower step bound on the integer mark while the hollow circles indicate exclusive at the upper bound:
Do note that a rounding graph would look similar, but would be translated 0.5 units, so that x=5.5 would yield y=6, etc.
