What do the headings in the table mean?

While the headings are fairly self-explanatory there is one could benefit from some explanation. That is the "Best Net Score to par". This is actually quite simple.

If you are playing a par 72 course and you shoot 80 off a 7 handicap then your net score is (you guessed it) 73. Now, if we compare that to par, you shot +1 (or one over what you would have been if you had played to your handicap). This is the number you will see under this heading. 

Another example might be that you played a par 72 course and shot 75 off a 7 handicap which means your net score is 68. Compared to par, that is -4 (or four under what you would have been if you had played to your handicap).

We like this because it shows very clearly how much better the round was compared to someone's handicap and also, in golf, there is nothing cooler than having a minus number next to your name.
