I didn't trademark "Derp Test," so any variation in name and methodology is fine. A side step, 4 push-ups during the reload, or even some ECQC maneuver is all kosher.
As stated previously, the point is to force bullseye level accuracy on the timer, interspersed before and after a reload, while confirming POA/POI and how your pistol/ammo combination does. My only concern about the scaled targets, shot considerably closer, is it doesn't test POA/POI and accuracy like 25 yards, and allows you to get away with some target focus that won't fly for most at 25 yards.
I guess the B8 would work, but that is so old school, where the "Derp Test" is a happening 2014 kind of test. If you haven't been using USPSA cardboard targets, I would suggest you try some along with matching pastors. These targets last a LONG time, while continuing to look great. My PF paper targets quickly look like crap, when I don't replace them, as should be obvious from some pictures of groups I posted lately. Our standard target array is 2-4 MGM 8 inch steel challenge type targets, and two paper targets stands, where we run one USPSA cardboard and one PF paper target on a PF sized cardboard backer.
