You can perhaps just happen to hit a rock or something in the sand and kick it out. I don't think they meant it to be deceptive, but I see issues with there tests not really looking to be unbiased. You would have to sift out the sand, then pack it to a consistent bed, and it would only test one bed type. How can you get a consistent rock or weed bed to test? It seems to me most importantly that the "new style" anchors seem to work better from all accounts. I don't think there is that huge of a difference between the major players. As long as you feel the manufacturer will stand behind the product and uses quality materials then I think you will get a good product. All of the "new" anchors seem to be close enough in design I doubt you would really see a difference in real world use. It is not like in the days of truly different designs between CRQ, Bruce, Danforth. Just find one that fits your bow roller and you are likely to be happy.

The ultimate "fair" and more scientific test for holding power would be a massive test tank, 80' long X 10' wide by 6' deep or so, with known consistent sifted media & water in it.

The machine would be on a vibrating base, like a soil tamper, and vibrate the media/water back to the same consistency after each drag. Drags and loading would all be computer controlled so as to impart no variations in testing.. Then and only then can truly fair holding capacity comparisons take place with a known consistent media...

With a test like this we can then A/B holding power for that particular media & anchor which could be loosely extrapolated to "general" holding power ratings across other mediums...
