Since David Presser and Bob Koca said that they didn't quite understand David Rockwell's point, here's a simpler example that may illustrate the point.
In a money game (without Jacoby), you could conceivably make a checker-play error that takes you from being too good to double to your opponent being too good to double, costing you over 2 points in equity. This isn't possible at DMP. Thus larger EMG errors are possible for money than for DMP.
If this is still too abstract, try taking the same position and making the "same" error at all four major match scores, and compare the EMG values. For example, try playing an opening 31 as 8/7 8/5 and see how big an error it is at money/GG/GS/DMP.
You could of course argue that this effect should really be explained as follows: It's easier to play at GG (for example) than for money, because you can't make the mistake of losing more gammons. But however you choose to explain it verbally, your PR will probably be lower at GG than for money even if you play the checkers exactly the same way and make no cube errors for money.
For those not already aware of it, Jeremy Bagai has written a very nice article on some issues with EMG. The article used to be here, though when I checked just now the link was dead. Not sure if this is a temporary or a permanent problem.
