Science & Industry

Hello Eve people,

Found something unusual and i thought i would share.

I usually tend to set long (around 30 day) manufacturing jobs, using excel sheets to work out which items will bring the most profit etc.

Using an example of a researched T1 veldspar mining crystal at a high sec station, i receieved a manufacturing quote for a single run which would take 77 seconds.

I've calculated that there are 2,592,000 seconds in a 30 day month, so the maximum number of runs (without going over 30 days) should be 33,662 runs.
However i recieved an info box saying that "Production Time Exceeds Limits" : 30 days 2 hours 30 minutes and 5 seconds.

So after some messing around with the number of runs i discovered that the most you can have within a 30 day limit is 33,545 ( with 35 seconds to spare).

I worked out it takes 2,591,965 seconds to manufacture 33,545 runs, which means that each run does not take 77 seconds precisely but a strange 77.26829631837829YadaYadaYada seconds.

Assuming i have not made any errors (oh the irony) this seems like a strange way of doing things, in fact im not totally convinced that this deliberate on the programmers part.

Personally i reckon it would make more sense if Manufacturing Times were that of the quote rounded to the nearest second and be done with it, or else we run the risk of other bored industry players making difficult to follow forum posts about nothing of particular importance.

Your thoughts ?

Anywho, here's some additional info.

I was bored

I manufacture a range of different items, i picked veld crystals as an example.

Seriously bored.

Right, im off to make a sandwich and stare at Asteroids for a bit.... possibly internet boobs as well.

Fly Safe y'all

As you have discovered, Eve Math is a weird mix of calculations done in ways that are not always logical or completely understandable. however, it does work. mostly.

Basicaly what you have discovered is that manufacturing jobs are calculated out to a large number of decimals and then rounded to the nearest second. Im betting that three runs of that veld crystal take 232 seconds rather then 231 seconds. however its not important enough for me to check.

if you look there are many things that are calcuated out but rounded when presented to us.

another notable example is security status and corp/faction standings. those are rounded out to four decimals but present two.

I posted about this last year, filed a bug report and hey whatdya know, ccp took a very keen interest in industry and ...... completely ignored it, never got a reply.
