In bowling terms,
resurfacing implies that the track has deep and many scratches that affect the roll/hook on the ball, making it hook very early. The scratches need to be removed, mostly, with very rough abrasive, around 180 grit (some use even rougher) and then the ball is brough back up to specs. This was much more frequent occurrence in the old days where people used one ball for years. Such gradual use blinds them to the constant small changes in ball reaction until one day a look at the track shocks them or a friend to noticing it. These days this happens much,much less frequently.
Refreshing implies the surface finish is no longer at true stock, out-of-the-box condition. It may be that some of the shine caused by polish has been removed or it had a P4000 grit finish and has been used enough games (maybe as little as 9 - 15 games) and needs to be touched up gently with a P4000 grit pad or polish, as needs be. In such a situation, often you may be barely able to see the change from stock BUT you can see it in the ball reaction.
