220.87 Meter Readings

[wirebender]

This is an excerpt of the meter billing on a project I am quoting.
the 1.58 in the Demand Rdg column is the highest over a two year period.
How do I use this for 220.87 Determining Existing Loads?

you probably can't read that, but I don't know how to enhance it

The columns read:
Reading......Usage/day.....Billing Mult...............Demand Rdg .............Demand Rdg Dt/Tm...........KWH Usage/Day
20125..........4...................60...........................1.58..........................03/01/2018 00:00:00 4 X60

Service is 208Y/120V.
Original load calculation on panel schedule was 186.539KW = 518 Amps.
heat load was 91KW

So, what I'm thinking is you multiply the 1.58 times that multiplier of 60 which would give me 94.8KVA which would be about what I would expect in the dead of winter with 90kw of heat in the building.
Multiply that by 1.25 per 220.87 gives me 118.5KVA.
600 AMP 208 service = 216KVA
216 - 118.5 = 97.5KVA or 260 amps available.

Am I thinking right on this?
