Final Valve Adjustment

I've probably done my final valve adjustment.
I've done 4 since I bought the car; first 3 a little over 20k miles between, then got lazy and skipped one, so the last was after about 40k miles.
Nothing's changing measurably, so I'm sure I'm good for at least another 40k miles, which will put me over 200k miles, should I be so lucky.

Attached is the spreadsheet used to record measurements and calculate changes. Might come in handy if you're going to do your own and don't have a spreadsheet already, or if you're wondering how they progress "typically", (your results may vary).
When I did it the first time I realized I needed some way to record how tight the feeler gauge went in. Decided to rate it on a scale of 0-9, and "invented" a fourth digit.
So 0.0nn0 means I was able to find an angle to get the gauge to go in, but then took a breath and moved slightly, and had to work hard to find the right angle to get it back out.
0.0nn9 means I could throw the gauge in and out with ease, but try as I may I couldn't get the next size to go in.
It's a little subjective, but good enough.

It's also worth noting that out of the 23 shims sizes that come with the standard BMW kit, I've used 3:
2.32 mm
2.36 mm
2.40 mm

Mine was the same way on my last 2 valve adjustments. Actually, didn't really needed any shim to be swap. Only reason we changed a couple of them was because "Kaiv" was such a stickler for getting everything smack in the middle as much as possible. I'm considering skipping a valve adjustment on the next inspection and just do it on every inspection2 instead.

"I've probably done my final valve adjustment.' This is sad.
