How are Charges Calculated?
I've been running a 512-droplet for $0.007/hr and my charges statement tells me I've used it for 40 hours.
40 * 0.007 = 0.28, right?
Well, the statement calculates $0.30. I've noticed this (mis?)calculation also in the November statement. It's not much, but how is DO calculating 0.30 instead of 0.28?
