How the math works
Every arrangement is the same three variables with different values: hours owed, in-kind value received, cash moved. A site-only volunteer post has a cash wage of zero. Hours-for-site-then-hourly has the first block in kind and the rest in cash. A wage with rent deducted is all cash with a negative flow. Effective hourly is the total of site value, utilities and cash, divided by total hours worked by everyone in the rig.
The hours basis is the part most listings leave out, and it's the part that moves the number most. Twenty-four hours per site and 24 hours per person are the same sentence and twice the work.
