Those results are for the block Cascade. But with some more restrictive blocks ( like those we use in Europe such 1A or nexxos ) the best choice is for lower pumps.

For a block like 1a-hv2, the best choice would be the MCP650, MCP600 and probably the DDC and CSP750 instead of MD20.

For the cascade, the DDC seems to have the same figures than the EHEIM 1250 (about 5.2 lpm and 9W) but with a more restrictive block, this lpm are less affected than for the EHEIM or IWAKI.

this topic is very usefulll to give an idea of why bigger pumps aren't the best choice, but I think you should put your figures into concept and say this results are valid for the cascade or others blocks with the same C/W and restriction, and that the best choice could evolve depending of the type of block (less or more restrictive).

It would be greet to do the same thing with many representative blocks, but I know data are missing.
