I don't think any Marriott MF's are priced "per thousand?" For Weeks they're established by the individual resort BOD/HOA -
here's the current 2012 MF thread.
Here's a recent thread with Nov '11 pricing for the DC - Points cost $10.94 each and MF's on those are .41 per Point.
If you compare ownership of a Week and its corresponding MF's to the equivalent DC Trust Points, I'm pretty sure it's a given that MF's are overall higher for the points. Exceptions might be the lowest-demand intervals but in order to use purchased Trust Points for those intervals you would still have to purchase the minimum number of Points - 1,500 for new owners and 1,000 for existing Weeks owners - to get into that system.
I'm actually a little bit confused by your post, seeing under your name that you own a Week, so I'll add this just in case - Weeks Owners who enroll their Week(s) into the DC and don't purchase additional Trust Points, do not pay MF based on the Points they're allotted. They still pay based on the MF's set by the individual resorts for their Week(s) but in addition to that they pay the $165/$199 annual Club Dues.
