Alright... well according to what I wrote at 4AM, from 105,000 miles to 106,000 miles is 600 miles.

Let's do some Math here:

Today at 4AM
106,000
- 105,000
__________
000,600

Maybe if I was rounding, then I'd consider it to be correct.

Let's "get down with the get down" and do the real Math here, eh?

Last service record states on Thursday, I was at 105,066, so let's say i drove a bit on Friday, before I left on Saturday, and say the trip started at 105,080, and ended at 105,658.

Begin Insanely Difficult Subtraction (!!!):
105,658
-105,080
________
000,578

Well, at least the estimate of 600 miles was correct. Remember kids, don't do simple subtraction under conditions of slightly impaired druggedness in the wee hours of the morn'. People die.

Hm... what the hell's a "soma"?
