It's been that way since 1991. If Disney saw a need for re-allocation it probably would have been adjusted, at least some, by now. There was an adjustment at OKW in 1996, but it didn't effect the larger weekend points vs weekdays.
Basically, DVC has had opportunity to adjust the point requirements as each new resort has been added. When BWV came onboard, they did create two tiers of points (Standard and Preferred).
When VWL and BCV came onboard, DVC ignored an opportunity to modify the
point charts and simply assumed the same chart used for the BWV Preferred View category - but eliminated any lower "Standard" point category.
When SSR came onboard, DVC did take the opportunity to make changes in the point charts and again with AKV some variation is taking place with variation in the villas themselves as well as the point charts.
While DVC does have the ability/authority to change the point charts (and certainly did that at OKW), I don't expect any significant change unless there is a drastic outcry from members. I would instead expect to see minor variation in the point requirements as new resorts are added to the program.
Here is the DVC
point chart for OKW from 1991 - 1995. In 1996, the current point chart began and is still valid at least thru 2008. The greatest changes made were for Adventure Season, where all room types increased. All other seasons saw little or no change on weekdays, but larger decreases on weekends for all room types.
