One has to judge even the M-K numbers using a bit of logic. Many clusters allocate sales to stations for "looks" and they don't match sales demo delivery. The idea is to comply with M-K reporting, but not to reveal which stations are the real sales leaders.And I'm sorry, because your numbers aren't anywhere near correct.
How about all these stations, which outbill KMNB...

KSTP-F
KXXR
KDWB

KEEY
KQRS

and likely KTMY and possibly KTLK.
I see Miller Kaplan every month, not sure where your numbers come from. I also saw Miller Kaplan when 102.9 was WLTE, and I'm 100% correct on that one.
In fact, even if a cluster is trying to be as accurate as possible, dividing the sales for a 5-station buy is really impossible. In those cases, I look at format appeal to advertisers, 18-54 and the common sales subsets, performance of the group owner on national sales and several other factors to weight the reported data.
This is, granted, a bit like guessing who really should have one Miss Universe when politics, race, alliances, ethnicity, language and the like are all take out of the results.
