No problem, Camille!
Let me add to it just a bit. The club I primarily shoot with hosts both SASS and W3G monthly matches on the same bays, using the same props, and using the same targets. The same people tend to shoot both types of match. In all cases, whether the shooter is experienced or novice, young or old, fast or slow, male or female, he or she is much more likely to shoot a clean W3G match than a clean SASS match.
Same shooters, same bays, same props, same targets. The only real difference is that for a W3G match the "bonus" centers - either knockout or overlay - are white while the rest of the target is black. For a SASS match the entire target is one color (usually black) and there are no bonuses. So, the generally-accepted reason for the improvement in hits is that the shooter is focusing on a smaller white-painted "target" in the center of the larger target. That way, even misses (on the center) are usually hits on the larger target.
