here is what I'm thinking,mom's mechanic is draining oil into common pan and then fill UOA bottle from there. does that make any sense or am I grasping at straws here?
next go around I will pull oil myself and see what shakes out.

Oh, I see. He's getting the oil from a 'multi-use' pan and not from the stream. In truth, this 'could' in fact affect the numbers 'some'.(effect? lol never learned that one well)

Just get on some ramps safely and do the oil change yourself or take it to a guy that WILL fill it from the draining oil into a sample bottle. Specify that need. If they won't work with you, go somewhere else.
 
I'd check/change the air filter. Si is high for the miles, and I'd bet it is contributing to some abrasive wear on the pistons - Al is somewhat high.
 
Whats weird is how low the zinc is on this latest sample. I`m thinking your theory may be correct.
