Some people use the scoring aspect of this game to judge how much they've improved, I have no problem with that.  Others however manipulate their score because of a frail ego and are interfering with the ones who wish to use scoring for legit reasons.  For that reason I think players should only be aloud to see their own score. 
P.S.  I find it funny how some players think they're so good because of their score, yet even I can spank them in a one on one.  Truly sad considering how poorly I fly.
