What's ridiculous is you not realising that a 12 inch shelf pulling
against a 1 inch bracket is a LOT of leverage. The bracket has to be
about the same height as the depth of the shelf.

I previously posted the calculation above that shows actual moment arm
is well within the product specs with at least a 2X safety margin.

And, YET AGAIN READ THE BLODDY SPEC SHEET!!!! -- the product description
shelf depth is 5-1/2" not 1-ft.

Spec sheets can't break the laws of physics.
And they're not coming even close to doing so here -- the rated load for
the dimensions is at least 2X less than the lower range of holding power
in soft pine as shown previously.

I'll stick to proper brackets which allow for leverage.
