"But no matter how small a yacht may be, I do not consider it is wise to use any type of patent anchor weighing less than 30lb., for although it may well have ample holding power once it had dug in, it may not be heavy enough to force its way through a layer of weed to reach the holding ground, and if it does not bite in quickly, its fluke may become so foul with weed as it slides along that it will not bite in at all. As a CQR of 30lb. is not made, I would use the 35-lb. rather than the 25-lb. model."

My take on anchoring is that it depends on two things. Firstly the type of seabed and secondly, but related, whether you are measuring ease and speed of setting or ultimate holding power.
For the last 30 years I have used a 25lb CQR on my boat based in Poole. It has never failed to set - except in the eel grass in Studland!. In fact the biggest problem usually is getting it to break out of the Poole or Solent mud.
Very different story with the boat in the Ionian. The original CQR was ok sort of in straight pulls when mooring at a quay, but did not always set and usually hopeless free anchoring - either because of weed on the bed, hard bottom or loose sand over rock. Replacement Delta significant improvement in all situations. Set quicker but arguably similar holding. Always had success with the kedge Brittany style where the pull was straight.
The other factor which one has to take into account, particularly if anchoring in tidal waters or with strong shifting winds is the ability to reset. I think this is a function of how well the anchor is dug in and its shape. The roll bar type seem to perform well here, although I remember being storm bound for three days in Newtown creek turning with the tide and being either head or stern into force 6s and 7s. CQR was well bedded in and never moved.
So the tests cannot hope to cover all anchoring situations, but understanding the characteristics of each type in relation to your potential usage helps in the decision.

I wonder if he would have stuck to his original equipment just because it was there, or if he would have made his own assessments along with listening to others.You never get to where you want to go if you only travel on sunny days.

The hoop would get in the way and make it harder to stow in the anchor locker

Well as everyone else is repeating everything that has been said before a zillion times, why not me as well!
The reason I groan at these ultimate holding power anchor tests is that for most of us that's not the issue. I can see why blue water sailors and liveaboards might put more emphasis on this, but for us coastal sailors in sheltered waters it's less important than how well and reliably the anchor sets in the first place.
We've all held the chain whilst backing down / digging-in to assess what's happening on the bottom, and by the time the damn thing has finally got a grip, we're now a few boat lengths from another boat in a crowded anchorage and have to up anchor and do the whole thing all over again! That's why I got rid of our CQR.
I would be far more convinced by video shots showing the ease or otherwise of our anchor choices actually digging into various seabeds. That's pretty rare footage in my experience (unless somebody tells me otherwise)...and THAT'S what PBO/YM should be doing IMO, not more load cell tests which I assume is what's being done here.

We like to remove the "luck" and human element as much as possible when testing anything. But unfortunately with anchors there is no one way to test them, the same way there is with rope for example.Yachting photographer http://grahamsnook.com/news
