...is there anything to learn from the ejection pattern of a semiauto when experimenting with load recipes?
Yes.

A group of cartridges loaded the same with the same bullet fired from the same gun by a shooter with the same stance and grip should eject cases so that they land - or or less - in proximity of one another.

For example, in my 9mm, factory ammunition travels about 8 feet behind and slightly to the right of me. The cases all end up in a circle under 2 feet in diameter.

So with that, I knew a load that kicked the brass 12 feet almost striht to the right was too hot without even having to inspect the brass or look at the primers.

If the cases are strung out all over the place, check how consistent the weight of your powder charges are.

Anything out of the ordinary when shooting reloaded ammunition (strange sound, strange feeling, strange ejection pattern, etc.) should be noted in your range notes and investigated.
