I just put together a percentage based cable loss calculator.
Notes:
- I am using my own server for now, but if my router crashes and my auto update script doesn't work I will end up with a different IP than the one the link points to (strangled is a freeDNS service). Resulting in it being down.
- IC2 rounds up when the power arrives, for example if you have 4 blocks of insulated copper cable you lose 4% of 32 EU. This is 0.96 EU, so you have 31.04EU which is rounded up to 32 EU.
- Note that the resources part lists the amount of materials that will be needed, not used. For example if you put in "13" it will say you need 9 copper for uninsulated copper cable which actually makes 18 cables (because you can't make exactly 13 so it rounds upwards to the nearest possibility).
- The wiki is wrong about Glass Fiber cables. It seems to have wildly changing estimates (namely 20 and 50) however I have tested it myself and confirmed that the loss is 0.025 or 1 EU every 40 blocks (the wiki has the same loss value in some places, but says that that means it loses 1 EU every 50, not 40 blocks which is wrong (try 0.025 * 50 and 0.025 * 40)).
Please report any bugs on this thread.
