The problem with this as with any sport is that we always want to better our scores regardless of fun and our competitive natures .
If your goal is to get 40 , you reach that then you want 41 , 42 and so on thats how it is Martin
IIRC your PB is either 49 or 50 which is good considering you rarely use the PCP or practice , so what if the wheels fell off - you are certainly not alone .
I remember last season and we all walked along the Swallows course thinking ' doddle this looks , easy clearance or very high 50's ' ... I like many others scored below 50 that day !!!!!
