Well, there isn't a standard rate. There is more than one agency, and they do not all pay the same rates. It's not like every agency paid every owner $x per point during 2024.
If I wanted historical data, I probably would try to find out how much owners were paid, per point, for using
https://dvcrequest.com/ over time. Getting info about just one agency over time would give you some consistency. And if you were to use
https://dvcrentalstore.com/ you need to know that they sometimes change what they pay owners throughout the year, depending on supply and demand.
Currently,
https://dvcrequest.com/ pays $18 per point for some resorts for reservations more than 7 months in advance. It pays $16 per point for other resorts, and for reservations less than 7 months in advance. They may have changed those rules over time.
