It looked to me like they only had one guage and were simply measuring a single point of pressure and flow rate. The pressure vs. flow rate would still represent a relative bit of information where higher the pressure the more restrictive, that's good...but the pressure drop piece didn't make sense. For pressure drop you need to measure pressure on both sides of the block simultaneously (two guages) or use a manometer with a + and - input. Regardless I was still happy to see some flow rate type testing included.
Im also interested how they measure pressure drop with only one guage. I think they measure pressure vs flow of setup with pump, then measure same thing in setup with waterblocks and subtract it from 1st data (only pump numbers)... i hope u get it

I have 2 guages and flowmeter, so if u ppl want i can measure pressure drop vs flow today/tomorrow and post numbers here.
