It could be your M8 rangefinder setup. There is a near focus and far focus adjustment that they make and by going through a few iterations, they come to a balance where the rangefinder works throughout the range....seems to be consistently backfocused under 2m, looks like something that could be easily adjusted since it is very consistent. I guess the technician shaves the focus cam a hair between these distances?
