Diamond has a fixture for mic'ing pistons that make it easy to be consistent but there still is a lil variation although usually less than you were getting. I know you are very detail oriented which is a really good thing with engines so I am not talking about you in particular but I taught people to read micrometers for 7 years and it does take some time for someone not doing it every day year after year.
