We still need the real test.

Where do you think any possible weakness would lie?

Basically the full weight of a massively obese person
falling on the bar vertically, pushing it down with the
lever action of the short horizontal legs to the wall.

Suppose someone did slip and grab the rail, putting the whole of their
weight against it, vertically,
horizontally or at an angle: what might happen?

The plugs thru the tiles pull out with the top screws
with the bottom of the round plate with the screws
thru it acting as a hinge against the tile.

The woodscrews be pulled out of the timber battens?

Did you manage to get all of them into timber battens ?

I thought you said that that was only possible at one end ?

The entire half-height stud wall give way?

That's possible but less likely.

The rail itself break?

Shouldn't happen if it was designed properly.

I'm not saying that any of these outcomes is an impossibility, simply
trying to understand just what the possible danger might be.

The first one imo, particularly if all the screws don't go into timber
battens.
