Very little about the reward program makes sense on the surface. And, no, there isn't a fixed award chart; the number of Avis Preferred points required for a comp rental is based partially on price and, much more significantly, whether they expect to rent out most of their full class fleet on the requested dates.

Frankly, they're loathe to comp a car that otherwise stands a strong likelihood for cash rental. Even taking this into account, I'm surprised by my results for this HI rental.
