I added M10 support to Joerg's script, using Ant's hint (thanks).
Made a LOG run with focus step set to 5 (an arbitrary value), using the EF_M 15-45 @15 and @45 mm.

Attached the plots for the EF-M 15-45.

Do you happen to know where those values are populated? 0x244918 is inside a huge structure and is not referenced directly (the firmware's addressing is very hard to follow, lots of base + offset variations).

Are there any other values where logging would be worthwhile?
For example, an absolute step counter?

I don't know, I did not look. The address you're getting the distance data is inside a big struct that has all sorts of lens related stuff (some are bytes, some are halfwords, there might be words too). If you read from neighboring addresses, you may find a counter (if it exists).
