Your average currently is 61.76. That last stroke off your average can be quit grueling to say the least.
As far as your average goes.... it doesn't go by how far under par you are as much as by your over all score, meaning, 9 hole scores are doubled and you 18 hole score is what's used for your avg.
For instance... a 9 hole score of 31, depending on which course it is shot on, could be -3 or -5, but the "31" itself is what is used toward your average and that 31 would be doubled to count as a 62 for your average score. That 62, since being higher than your average, won't make much of a difference towards your average calculation.
