Hi Wes, understand why you chose those dates but this arbitrary one-month period may be misleading. For example, just got back from one trip. That equals zero in your calculation. Heading out Monday on a trip to Asia for over a month. Since I won't be back until after 10/26, another zero.
If you want to 'cheat' and stretch this out another 10 days, then it would be over $7K.

Point being, neither is typical, just a brief quirk in time. Better to look at an entire year to minimize events like this.
