The power factor appears as you type, worked out the way the match will score it.</strong> That matters more than it sounds. Most power factor calculators multiply and divide and stop there. The rulebook then does two more things that decide whether you pass: it throws away the decimals, and if you fall short it re-shoots under rules that differ between USPSA and IPSC. This one does both, and it also tells you how much margin you&rsquo;re carrying into a cold morning.</p>
