Everyone's mind works differently, so please dont tell anyone they are "sad" for thinking that way. You may be able to see how you play with simple memories, but my guess is you would learn quicker if you had statistics to back your "memories" . . . I need comparisons and statistcis do not lie expecially when you consider the mount of rounds we are talking about with me . . .. I play enough for the statistics to really matter because they are a true average. If I only played once a week or something they wouldnt mean as much, but when I play an average of a round a day for almost 2.5 years they mean a lot!
Bear in mind I am not saying "everyone should keep score" but I think keeping score would help everyone regardless if they think it would or not . . . just as I think not keeping score might help me improve because I am not thinking about my score, but for now I will continue to do so. It worked for me in the golf world, so I think it will help me in disc golf too.
