I never said that every shot should be the same. Having a tournament standard for the height of the basket off the ground, or "playing surface" would not be a bad thing. That's all I'm really saying.
It would be impractical for most tournaments, which are held on existing courses, many of which have baskets of varying heights. Players would rather have tournaments on these courses, than not. An argument could be made for a tighter standard on top events, though I'd disagree with that, too.
I think there are guidelines that you shouldn't have more than 1/3 of baskets at non-standard height, and that hanging baskets should be secured, at least for higher-tier events.
Target sizes are standard, but their placement need not be. Targets at different heights test different skills, putting styles, and decisions, especially in places where there is no little natural elevation to use. These buried baskets are a bit gimmicky, but they're also a bit challenging on long putts because of the different angle. Players are still throwing for the chains, because intending to skip or slide in is risky; discs kick one way or the other, or stop short.
