That's the way it should be done. Having a review period saved me on my master bump. No one else noticed that the classifier was missing 5 points. Two stages on one pit, the popper was added to the wrong stage.
For the USPSA upload, I assume it's a fairly painless process? I run the tablet's for my home club's action pistol match, but I might volunteer to take on another club's USPSA tablets.
Currently for reasons unclear the MD uploads all the matches for the year at once in December, rendering the classifiers for most of us invalid.
