That may have been the biggest boondoggle FW ever published
loose tenon joinery is as strong as traditional M&T which is by far the best perpendicular joinery for _wood_ period.
there are cheaper solutions than Festool (one is promoted here regularly)
Other than that there is not much else to say.....

Domino is a brand name- I call it "loose tenon".
What does that have to do with where I live? It just happens to be the best rock on the block.

Unfortunately that test was nvalid. Moden gluees as used are much stronger than the wod so what was measured was the glued area of the wood. Unless you are into timber construction the question is pretty meaningless.
I've had a ill considered application where sound white oak broke in the wood not near the jint and another were Ipê did the same thing.

That's what it looked like to me when I looked over the list. (except for "bridle" vs "Half lap")
But a follow-up question: How strong is strong enough?
Most joints you'd use a loose tenon, biscuit or pocket hole screw for aren't going to be severely stressed.

You never know where your creations may end up, esp if you move and things get stored. Movers are not gentle on things. I was shocked to see pieces I built under 100s of pounds of stuff in storage units. My blanket chest was positioned on its side with boxes of heavy books on top. We had a maitland smith table break. Best to build things for abuse cause you may not be around to keep an eye on it.

You are absolutely correct, I'm not sure how they came to be called dominoes (and find it irritating). Back under my rock, now.
I started with absolutely nothing. Now, thanks to years of hard work, careful planning, and perseverance, I find I still have most of it left.

There is no way I would trust a domino joint on a table, chair, or cabinet unless I reinforced it with pocket hole screws.

The Domino loose tenons are the culprit. The grooved surfaces don't allow much glue contact. Make your own hardwood tenons with smooth surfaces, and your joint strength will approach that of the floating tenon. If the furniture will see jumping kids or karate practice, use more than one tenon. Tenons are cheap.
Wood Magazine did a similar test in 2007 with similar results. They also concluded that all joints were adequately strong for joinery.

Flawed test. They did not include butt joints with staples, or miter joints with screws. I can think of a few more.
Those are nice to know when you are deciding to build a fish stand verses a music box.
