I have not shot a PRS/NRL match yet (planning too next year...in the process of putting a rifle together), but have competed in high power, long range, and small bore, and all those disciplines have classifications based on your percentage....your score vs perfect score (not high score), e.g. in high power if you shoot a 755 out of 800 gives you a 94% classification, which puts the shooter in 'master' class. 97+% gives you a high master classification (highest) and there are 5 classifications. So, at any high power match, masters shoot against masters, high masters against high masters, and marksmen (lowest classification) shoot against marksmen. And the same classifications are all squaded together so that they shoot in the 'same conditions'....a HUGE deal in this game. Meaning, masters shoot at the same time as all the other masters, so a change in the weather doesn't give one group of masters a advantage. Long range and small bore have a slightly different % classification, but you get the drift. AND....I'm assuming that PRS does not have a classification system, which, quite frankly makes no sense. But then.....I've never fired a PRS match....yet.
