I took 3 of my cruise bpo's which are at 50/50 for ME/PE (I have Industry 4, PE 4, Refining 4) and looked at the minerals required for 1 run, and did the simple math to figure out how much I would need to make the amount I required. I came out with these numbers:
devastator x 200 = 20k
iso: 4 = 800
mexa: 77 = 15400 (14600)
trit: 1370 = 274000 (274020)
zyd: 1 = 200
paradise x 200 = 20k
mexa: 64 = 12800 (12200)
pyer: 447 = 89400 (89450)
trit: 2920 = 584000 (583960)
zyd: 2 = 400
wrath x 300 = 30k
mexa: 16 = 4800 (4500)
nocx: 2 = 600
pyer: 137 = 41100 (39000)
trit: 1767 = 530100 (530100)
zyd: 2 = 600
The first numbers are how much for 1 run, the number after the equal sign is the total amount for the number of runs (listed above with the name of the missile). The numbers in the brackets are the REAL amounts of ore that the station required (the ones without brackets were correctly assumed).
Now, why are the numbers I came up with and what the station needed different? It was a Caldari Navy Assembly Poduction station, and I have a Caldari Navy standing of 9.88. The station info said it had 1.5% bonus of some sort for people with good standing - dunno how that factors in to anything though.
The station showed me as having 4.9% waste factor for pyerite and tritanium, which I figured OK, maybe that's why... until I made my batch of Wrath Cruise missiles... look at how much tritanium it required vs how much I calculated... yep - I was 100% correct. Now, why would I have been 100% correct on that with a 4.9% waste factor, yet INCORRECT on the other two?
Also! If I had 4.9% waste, why did some of the missiles require LESS tritanium and pyerite than I had assumed?!
What is going on with the math in the game/station? Is this a bug, or is there something about production I don't know about?

Anyone? Dev, GM... is this a bug, or is there some game mechanic I'm just omitting in my calculations?

I ran into similar "problems" when I built ammo, I'm not sure what causes this but I think it has to do with how EVE rounds material requirements in BPOs, especially if you use researched BPOs and non-perfect crafting skills - I noticed the quote window showed 0% waste on (low quantity) minerals, and sometimes slightly higher than what I expected from only having PE3

No, I highly doubt it can be the rounding of numbers - the %'s are all different, and in fact, the % differences are HIGHER on the smaller quantities than on the larger ones. If it were a rounding issue, the larger quantities should be off more than the smaller quantities, but this is not the case.
Something is seriously messed up, or there's something I've missed - no replies yet from any ISD members or GM's yet has me wondering if it's some kind of hush-hush bug - then again, why aren't any of the people who do nothing but manufacturing not complaining about this problem as well (aside from it seems that it's saving us ore :P)?

I have seen screwy stuff like this as well with PE4. I've done builds where the waste on some materials is 0% and on others is 15%, when both should be ~5% due to high ME and me only having PE 4.

Ok, so bug. I'll send in a bug report and pretend CCP is fixing it :P

Its fairly stupid actually.
Waste factors of blueprints are rounded so once you have perfected your craft at Production Efficiency 5 you dont get any difference between the quote of one run multiplied with number of runs and the quote of multiple runs.
Waste factor that is due to the inefficiency of the builder is rounded after the number of runs, but ONLY if there is waste on a one run quote. So if your inefficiency waste factor is 5% and you have a a Blueprint that requires 78 pye you will get a quote of 82 pye on one run (the actual number is 81,9 so with 200 runs the build reqs are 16380 instead of 16400. If the blueprint reqs (perfect) are 83 pye you get a quote of 87 (actual number is 87.15) so with 200 runs you get a quote of 17430 instead of 17400.
Sometimes the waste factors are so close to a whole number on 1 run that it takes 1000s of runs to get any discrepancy.
For example if one requires 1920 trit you will get a quote of exactly 2016 trit for one run and there will never be a discrepancy.
Your 4,9% waste may be due to your extremely high standing, not really sure about that.
Hope this explains it.

Ahhh, hmm that does explain it! I was under the impression that they would do the rounding on a per run basis and then use that *WHOLE* number to base the production of multiple runs.
Ah well, bug report already sent in :) Maybe one day CCP will finally be nice and show us the *FULL* number in brackets or something so we can compute more accurate production runs... having extra minerals means transporting more than you needed to carry - coming up short is even more of a PITA because it means either spending high isk values to get some at the station if it's there, or going back for another hauling run! That is... if your minerals aren't kept where you do assembly (which is my case).
