As title, getting a 1MW power usage and it scans EXTREMELY slowly. It might take up to 10 mins for a single sector. This is using a bob's mods radar MK2, with 2 amp researches and a single efficiency.

Also affects vanilla radars. If you want any specific info just ask :D

(edit) completely redone, as I screwed up.

change lines 10 and 51 from
(10000 * (1.5 ^ radar_amplification_type) * 40)
to
(10000 * (1.5 ^ radar_amplification_type))

Explanation:
By default in big brother the energy cost scaling is additive, meaning if the default scan time is assumed to be 40 seconds (as is said in the code comments) you have to multiply the extra energy cost per second by 40 to cancel it out in the sector scanning cost. This mod changes the energy cost scaling to a multiplier, meaning to get the same cancellation you should just have to multiply the cost per sector by the same factor as the energy cost, not an additional *40.

You are correct, thankyou. I'm not sure why I missed that.
