Collision,
As promised in my last email, the comparative maintenance figures up the
big end of the Golden Age of town, the G3TL12 Tigress-class DN:

Yours for the low, low price of MCr471,843!

According to its writeup on GT:S p101, that means 3,297 man-hours of
maintenance each day.

Turns out such a Happy Fun Ball mounts a bit of power generation too:

Propulsion demands: 1,858,140 MW (250,000 MW for jump drive, 1,608,140
MW for M-drive)
Weaponry demands: 200,237 MW
Meson screen demands: 1,565,200 MW

Assuming that can all run full-banger at same time, I get a total power
demand of 3,623,577 MW.

By the looks of it, one of these puppies could put down on CONUS and
provide the contemporary Americas' total power demand with no
supply-side issues.

Elv maintenance = sqrt (3,623,577,000) * 0.010 (TTL14+) * 1.0 (fusion) *
1.0 (starship) = 602.0 man-hours/day.

So yeah, looks like you can punt the 4.8 scaling constant out the window
and save yourself a lot of effort.
