Hello,

Minecraft Version: 1.19.2
IndustrialCraft 2 Classic Version: 2.1.1

Description of the Issue:

There seems to be an inconsistency between the in-game wiki and the actual behavior of copper cables. According to the in-game wiki, copper cables should be able to support up to 5 blocks in length without any energy loss. However, based on my tests, energy loss occurs when the length exceeds 4 blocks. For a transfer of 40,000 EU, only 38,750 EU is successfully transmitted over a distance of 5 blocks.

I also conducted a test with gold cables, which the in-game wiki states can support 2 blocks in length without energy loss. In this case, I observed no energy loss over a 2-block distance, which aligns with the wiki's information.

Steps to Reproduce:

Set up a power source generating 40,000 EU.
Connect the source to a destination using 5 copper cables.
Observe the energy received at the destination (38,750 EU instead of 40,000 EU).
Expected Result:
Copper cables should transmit energy up to 5 blocks without any loss, as indicated in the in-game wiki.

Actual Result:
Energy loss is observed when using copper cables for a distance of more than 4 blocks.

Additional Notes:
This issue does not occur with gold cables when used for a distance of 2 blocks, consistent with the in-game wiki.

Thank you for looking into this!

This is mainly a wiki issue.
The loss is exactly 0.2... So technically you can go up to 5 blocks before you lose anything.
4 Blocks + machine.

But yeah this is something we just need to adjust in the wiki...
