That fraction of a second difference in split times may not look like much at first glance. But in a 100 round match, with all paper targets that require two scoring hits, there will be 50 splits. The shooter running .30 second DT splits will spend .15 seconds of their score achieving them. A shooter using all CP splits (with a .60 average time) will be spending around .30 seconds to achieve their second hit. That .15-second difference is huge in the final standings! And a clear advantage to the Double Tap.
