I've not been able to find anything on the board already that covers the calculations used for negative ME invented blueprints.
The standard calculation does not work, as at me -1 you hit a divide by 0 problem, not to mention that -ve ME would actually save minerals.
Has anyone done any research yet into what the formula might be?
Based on a little trial and error, I arrived at the following formula:
BaseRequirement*(1+(0.1*(1.5-(ME/2))))*(1.25-(0.05*ProdEff))
Note, I've only checked this against two bpcs, both of which were me -9. The 1.5 part doesn't really seem right to me, I'm guessing that this just happens to have worked out at me -9.
Anyone got any other theories?
I'll try to sort out my calculations over the weekend and see if I can get something better.

How did you get ME -9?
ME -8 and PE -3 is the highest you should get for invented BPCs.

Of course I do...
Its pretty simple really. Unlike positive ME, negative ME seems linear.
As you probalbly know ME affects the wastage level, so thats what we are really looking at. THere are ling formulas decribing the development of the wastage when doing positive ME research on a blueprint.
Now negative ME works a bit more simple. The formula is: (-ME-1)/10
So as an example a bpc with ME = -7 will have a wastage of (-(-7)-1)/10 = 0.6
We can set up a full table for teh known ME lvls:
ME / Waste -4 / 0.3 -5 / 0.4 -6 / 0.5 -7 / 0.6 -8 / 0.7
(Note that this formula will be dodgy on ME closer to 0 than -2. I guess thats why you cant get that... )
So how does that waste influence you? Well thats simple really: BaseRequirement*(1+waste)
So if the base material need on something is 300 and you have an ME -7 bpc you will need 300*(1+0.6)=480 units of that material.
Hope that answers your question.

maybe I was tired! I checked against a couple of BPs on contract, I'm sure they were -9. Maybe I was squinting a bit and it was really -8!

Qual, by my calculations the effect of -ve ME appeared to be linear, I had been thinking that was probably wrong, though I can't think of any reason why it can't be correct. Does seem odd that it wouldn't be able to deal with me -1, though your calculations do seem nice and straight forward.

Yes, it is a "flaw" in the formula. Im working on the PE formula as well which has a similar linear formula as far as I can tell, but which is also strange moving from -1 to 0 PE.

You can get PE -4 by not using decryptors...

Doh!
Of course it should be -4, that's what I get for posting and working at the same time...

Great stuff! Glad I found this thread.
Can anyone confirm if the formulas from Qual do not actually need to consider the built-in waste factor (which is different for different kinds of items)?
Perhaps the 10 in the equation should be replaced with the built-in waste factor for each type?

I also notice that with ME of -1 you get 0 waste which is really nice Can someone tell me how to research my BPOs to ME -1?

About the non 10% waste factors, yes there are some although... it seems they are different by accident. It's pretty random. For example, check out most (all?) the projectile turrets. 5% base waste. Also I think all the probes and some links.
