I have a hard time believing that it can do double of what the other two can... unless you're just adding the flow of the two loops together which would be wrong... though since it seems to be conveniently just double the flow of the other two tops...
How would adding the flow of the 2 outlets be wrong? Your still only using one pump to run 2 loops.

The reason it puts out twice as much water had something to do with the way the D5 was built or something with a restricted outlet.. I recall seeing it being posted in this topic a few times..
