First off, if at all possible,, find a mentor or even pay a well known handgun instructor to at least teach you the PROPER basics of grip, stance, sight alignment, sight focus, trigger pull, follow-through, etc. It will be MUCH better than trying to break an ingrained, motor-memory skill that's incorrect.
That said, let's address your questions.
Group sizes. Normally they are measured at a specific distance, (say 25 yds) in both offhand & from a bench. Both techniques to properly do this are different. But they give you an idea of your potential & the gun's potential. And yes,, they are both carefully done in a slower, deliberate method. Speed is not your friend.
Action handgun shooters in a competition such as USPSA look at the fact that their scores are partially based upon speed. Scores are based upon speed AND accuracy. But the distances they most often shoot, combined with the size of the "A" zone scoring area can make for somewhat easier shooting than trying to get a tight group on a bullseye. But even in USPSA,, "Spray & pray" at top speed will not win.
So, by far,, I'd seriously suggest you look hard at finding an instructor or mentor with the credentials to at least give you the proper basics of how to shoot a handgun.
