I'm currently working on implementing a BPO Browser in EVEMon and thought on adding some additional info for each blueprint, like the prefect ME level a blueprint needs to eliminate the waste. So I used the equation provided from http://wiki.eve-id.net/Equations to calculate it. Will doing some alpha testing and playing around with the ME level modifier (it's a tool implemented in the browser), I noticed that the actual ME level that eliminates the waste differs from the calculation done by the equation.
So I've done some maths and came to the conclusion that the actual equation should be:
PerfectME = Round(BaseMaterialAmount * 0.25) - 1),0)
I cross-checked the result of this equation with the result that the tool gives me in the browser and they always return the same number. So, to me it looks accurate.
Can anyone else confirm my finding?

I don't see what's wrong with equation on eve-dev (I wrote it myself TBH)
Proper one:
2 * Fb * M < ME
or in percents
0.02 * Fb% * M < ME
Where Fb - base wastage factor of a given blueprint
M - material amount
ME - required material effeciency level to eliminate waste on that material.
If you take average blueprint with 10% base wastage, the calculation would give you either
2*0.1*832=166.4 < ME
or
2*0.1*756=151.2 < ME |

OK. Let's see it with my equation.
((756 * 0.25) - 1) = 189 - 1 = 188, which is the perfect ME level according to my formula.
188 ME level is actually 0.05% wastage factor (for the mentioned blueprint).
So, 756 * 0.05% < 0.5 and I don't say 1 because CCP is applying some serious rounding on material amounts. Even a #.5 result gets round up by CCP.
I will attach the patch within the week and when Scetrov commits it you can play around with the tool and see for yourself. I don't want to get into a debate with you, Tonto.

For the record: Perfect ME formula was derived from wastage calculation equation.

After having a good nights sleep and caffeine flowing in my system, I did the math and testing again. I realized that the truth lies between the two formulas.
Because CCP is doing a round up when the result return a #.5 value, the formula in EVE-Dev wiki gets off.
So the revised formula looks like this:
PerfectME = Ceiling((0.025 * WasteFactor * BaseMaterialAmount) - 1)

My posts may help.
M.E. is rounded-up (fraction truncated after adding 0.5). P.E. is rounded to zero (fraction truncated).
