In my reviews, I often try to suggest what level a course seems to be geared toward. But only in general terms (...feels like a Rec to Int course...) In the 'other' section, I also have a sentence about my experience, so folks can take my info with a grain of salt. On the cusp of Intermediate skills, I've only got my perspective, but a player with 15 to 20 years' experience above, say a 950 rating might also have a hard time relating to the masses, as it were. I'm sometimes able to read between the lines about what level skills other reviewers have (especially when they refer to a course as "short" because all the holes are from 320 to 450 feet, for instance).
