Not wanting to be mistaken for defending the seller, he could be a crook, he could be a saint, but the way the term CLA is thrown into conversations on the internet has devalued its meaning to the point that it is more like a rite of passage than a meaningful acronym.
People get the rangefinder adjusted and think they had a CLA. People have a sticky shutter adjusted and think they had a CLA. Meanwhile the people who know they had a CLA will be the ones wincing at the cost because it is far more than the throw away line lobbed into a conversation like 'just send it for a CLA', as if it is the cheapest and easiest thing to do. This is what devalues the term, and it is what makes back street repairers think they know what to do. If a CLA doesn't run to an A4 sheet of things checked, adjusted, lubed, or repaired it isn't a CLA in my book.
If the exposure is uniform across the frame id not worry it is possible to get a M close to nominal but id not expect that from a normal service unless it was at Solms.

Curious I test my Pentax KX which is almost 40 years old and I believe older than the M4-P. I don't think it had ever gotten a CLA.

Most Pentax used shutters which were near clones of the pre IIIc Leica shutter the nominal value is not imperative they are difficult to get uniform exposure across the frame the slit worth varies to allow for blind acceleration...
I sent the Leica back yesterday, I realized that it's better for me to just stick with my Nikon F4's.
thx for the help/suggestions though!
Wild. I was this close to bidding on that exact listing. I watched it and waffled. I wonder if it gets relisted. I might have another chance.
I use Gus Lazzari at TLC Camera Repair. He's on the "other" coast from you.
He did my M4P and a few lenses for me. 100% professional and is a frequent contributor on the Leica Internet Forums.
Best of luck,
Guess it's too late to change the past but how does your shutter tester work? If it's a light sensitive cell aimed at a light, then a penumbra could "start" the time count early and "end" it late, resulting in "longer" measured times than effective.
I'd rely on a sensitometric test, exposing frames at different times and compare 1/30th f/16 to 1/60th f/11 for example, working your way up to 1/1000.
