Looking over the description and math you provide about the Tier 1 coil, you mention that it has a 'Coil Throughput Multiplier', (CTM) however I haven't seen this referenced anywhere.
The table listing the research tiers seems self explanatory, and simple to calculate how much your power network is going to need to 'spend' to charge your equipment at the available throughput. If there's a hidden CTM that is acting on all coils at all research levels, then is it even worth listing as a separate factor?
I haven't personally noticed the CTM in my gameplay either - I seem to consume 150kw from my network with a single coil, not the 75kw advertised on the information tab here.
Basically just looking for some clarification so I can make these calculations easier for myself.
Cheers
