Kane.Blackmoon - I chose the numbers I did based on two things
1) The base you need to create to get to the medium power poles
2) The 'pain' threshold that Pyanadon wants to create for his mod :)
As a result, if you build bigger earlier, it'll be more painful yeah. I feel this is inline with the ash/lack-of-splitter early game design decisions.
All that said, I did adjust the numbers in this change to 27.5MW (small power pole) / 22MW (small fuse) to be based more on steam engine capability, give a one engine bonus if you don't use fuses and reduce the number of independent power stations you need to build on your way to py1.
I'd love your feedback and you can change anything in settings to meet your tastes as well, of course :)
