The DMD peak that I saw was 4700+ just before the banning.
If there are 4000 patrons, my guesstimate for the project preference would be : only there for Melody, 2000 ; there to support the studio, 1000 ; only there to indirectly support DMD, 1000.
Mrdots' studio showed the average patron level at $9+ (when this metric was enabled). But the HUGE diff now is I'm guessing almost all the lower-level patrons of strictly DMD preference have migrated to BMAC site. So, the Melody supporters who have replaced those migrants figure to be only about half the average pledge level.
Since the die-hard patrons of DMD have increased their average pledge level (by the voluntary migration being left out of this equation), it appears that financially it's close to equality between the 1000 DMD supporters and the 2000 Melody supporters, but only if we tip the 1000 studio supporters fairly strongly on the Melody side of the ledger.
As well, my guesstimate is about 2500 BMAC donors at ~$15 each. For argument's sake, count that at $5 apiece, monthly.
DMD seems to do about TWICE the business of Melody!
