Hi Cameron. Rack scores and match scores are the American (and more intuitive) way of keeping the results. The only thing this method fails at a bit is keeping track of runs.
The Europeans keep track of the run, by noting how many balls were on the table after each inning. So if player A misses after making 5, he'd write down 10 (and only 10 - he's not writing 5 anywhere). Thus, the incoming player will always know where in the rack he was when he began his run. However, the only way to accomplish this is to not have two separate counts (rack and match) like the Americans. In other words, in the example above, those 5 points the player made at the beginning of the rack would be added instantly to his total score, even in the middle of the frame.
While the American way isn't great at keeping track of the run, the European way is difficult to backtrack out of if a mistake is made at any point. And in frames where there are multiple misses/safes, it is confusing as well.
