Hello,
I'm trying to figure out how to calculate my own BoMs for BPOs based on varying ME levels. I'm aware that wastage = 10/(1+ME), and that BPOs off the market start at 10% wastage. So the issue is how to properly calculate any ME level BoM from that point. Rounding becomes the main issue. Ie, when do I round, and how (round up? Down? Just round to closest whole number?).
If someone could give me an example of starting with an ME 0 BPO BoM and working to (for the sake of arguement) and ME 15 BoM of something simple. Preferably small numbers in the BoM (that's where rounding errors have the largest effect).
Thanks! |

Thank you, although I'm aware of the math, and of the tools available if I want to use someone else's tool. But I have my own tools. The one thing that's always annoyed me is having to manually enter amounts on the BoM for different ME levels. I'd much rather just change the ME as an input on my own tool and have the BoM's update automatically.
I'll work out an example below of what's going wrong for me (it'll take some time... so I'll just edit this post over the next few minutes) |

Well, I've always found the BPO calculator to be accurate down to the unit - so run a few of your samples through your calculation, see whether they match up with the BPO calculator. |

To get the actual numbers you must first get the base value.
The values in the database dump are the base numbers already.
If you base your numbers off the Show Info of a ME 0 BPO, then you must first divide them by 1.1 (drones have only a base waste of 5%!!) and round. Rounding is always done to the closest integer.
To calculate the values for waste on any given ME level, use this formula:
Base Materials * waste factor * ( 1 / ( 1 + ME ))
This works for every ME level >= 0
For more info on negative ME or skill waste see http://wiki.eve-id.net/Equations |
