Pretty good...
... but you need to work on your scoring system. I tried shooting only bullseyes (got 11 out of 12 and 1 95%) and scored about 700 points. Then I concentrated on minimizing my reaction time, and I scored 1900 points mostly hitting the targets in the perifery. (Dunno how to spell this in english, sorry). Thus, I think precision should count more than it does right now.
