1.4k is a big drop therefore to do this would require something special not just more concentrated jets so it does suggest that the testing method isnt as accurate as the site suggests (they are also quoting the results in a way that should only be done if they can be accurate to 0.005k which they certainly are not, the testing page only shows them using a relatively basic setup. also they are using a tiny pump the will nowhere near be giving the sort of flow rate to make the blocks anywhere near what most users would expect (most eheims users would use a 1048 or 1250 which would give much higher flow rates eg a 1250 would give well over 3-4x the flow rate on a system like that)
