Symptoms of dirty pistons?

So this is the reading I got 20 minutes after I shut the car off. Slightly overfilled. I intend to run this M1 EP for 7,500 miles. Lets see if I really don't lose oil. Will keep reporting.

Do you suspect your pistons are “dirty”?

They all have carbon on the top. So, they’re all “dirty”.

Fixed that overfill, this is a serious experiment
