And what course has had the best renvation?
What classifies as a good renovation?
A great renovation?
Can there (has there) be renovations that actually make a course worse?

Renovations are entirely club dependent and what makes them good or great is ultimately going to rest with how the club and the players feel.
As for renovations making a club worse... it's a sure bet that happens a lot.
A lot on here feel a lot of the US Open restorations leave the club worse off.
But like with any club related matters, it's up to the club.
