Your comparator may be returning a lower than expected result due to the size or shape of the datum contact edge of the bushing.
If it is not perfectly square (or over spec diameter) it will under-report, and illustrates the possible inaccuracy of using an un-calibrated comparator.

Good Luck, YMMV.
