IMHO, it's no good to concentrate on the numbers. This is a game, a leisure, supposed to provide fun - concentrate on that and the scores will come by themselves.
OTOH, it's important to raise the level with XPs to be able to buy equipment when it's due (usually at Master tier).
You are playing almost all Starter equipment (the 3WD is missing, though) and Starter balls, so there's no commercial burden. Play along, check out the courses, meet friends, enjoy the views - to me, that's more fun than chasing numbers...
