Not to nitpick, but Roger said 3 passengers, which would be then divided by
4, hence $20 minimum.

I pay for the entire flight myself and haven't had to divide my costs. If I
can't afford to fly someplace without passengers, I don't fly...

$80 divided by 3 people is $26.67, not $20.

What the rule states (altho not clearly) is that the PIC may pay
exactly 1/3 of the cost OR upto and including the ENTIRE cost of
the flight.

Anything else is "compensation for hire".

The phrase "pro rata" translates to "fair share".
