Looks like excellent resuts. I would go 6000-7500 miles with it and not switch to the 7500. Copper will come down with time I would guess but all else looks great!

similar wear result from previous uoa(20 weight) even though this oil has less(calcium, etc);refilled with 5w20 M1. Will try MDC 7500 5w20 on next interval.
 
I am reluctant to go 7.5k OCI, flash gets too low for my taste. Perhaps I would do a filter change/top off at 3.5k if I go this route. I suspect I could get same result with the 7500 on same miles for half the price.

AL, yes the copper(and Iron) is indeed coming down on every change. 20 weight is what manual/oil fill cap calls for.

I can certainly understand that but you really don't have any issues that I see-no Na/K (coolant leak) and insolubles are low. You certainly could go further than the milage you went and not feel the least guilty.
