I don't see the need to add the 20some review to a well-known course (unless it is to right some wrong), so I try to focus on putting new or little known courses on the map.
Being starved for Discgolf for so long, my overall credo is "Any course is better than no course". Therefore, I always try to focus on the good things, as someone went through all the hustle to create something for us to play on. Objectively, I might be a little bit more lenient on rating European courses in comparison to U.S as we are still a developing country in terms of Discgolf infrastructure (except Scandinavia), so you can't be too picky here.
