Once you achieve Legend tier you start playing from the back tees and once you make Tour Legend you start putting on 13 speed greens and that's it...
Champions and above are just better at or at least more consustent at scoring low in ranked games with those conditions...
If you play 'alternate shot' or other multiplayer games then the conditions always default to the highest tier player with Tour Masters and below just enjoying play off shorter tee boxes...
I hope that answers your question...
