To analyse performance with regard to Nash's functional/dysfunctional model we must first look at what this model represents. Nash's functional/dysfunctional model represents the idea that each performer behaves differently whilst playing their sport, due to their personality. It ranges between +3 and -2 but the average player will be around a 0 and +2. However, a person may have an experience or have a reaction which could be classified as a -2 reaction even if they are normally a type 0 or type +1. At the highest most functional end of Nash's scale, is the type +3 person. These people...
who abuse the ruling and have outwitted them by rising above it and performing better than them. This has then resulted in them becoming increasingly more agitated and eventually making a mistake which has been noticed by the umpire, or them injuring themselves.

Overall I would say that I was a between a +1 and a +2 player depending on the game or my mood on that particular day. It is important to remember that different people have different personalities and at that will reflect their way of performing either as part of a team or as an individual.
