Only problem with the Maggie measurements is that planars are notoriously hard to measure, particularly with regard to the integration of the backwave. In this case you are comparing apples to oranges.

In addition, the beauty of the NRC measurements is that they're done in an anechoic chamber and measured in a similar way. You can't really compare the Stereophile measurements, as they're done in a living room using MLSSA. So again it's apples to oranges.
