Yes, as it stands the results with the Eheim 1260 have marginal correlation with the results of the blocks with the Eheim 1048, but JoeC doesn't mention this.
The RBX has 4x the pressure drop of the SlitEdge, but is receiving the same flow rate as the SlitEdge due to the 1260 being used.
Again, not a major deal, but if JoeC wants to compare apples to apples using his chosen measurement methdology, then he really should be aware that he's just gone and slanted the test towards the RBX, and away from the other blocks tested.
