Remember, it is not just radius that determines a corner's severity, but also how many degrees it turns through, and banking or adverse camber will impact this as well.
The number of corners on circuits can give a general meter, but is going to be most useful for circuits at either extreme (i.e. those with very few or a huge number of turns). Numbers of turns per mile can be rather useful, especially when you know the tracks you're looking at, as it's unlikely you will have a track that has that many flat-out turns all in a row, or that many flat-out corners in total really.
For a shorter, club circuit, like Knockhill, having a straight or "straight" of 600-700m should be fine. For something longer, say, starting at 3.0km in length, you probably want at least a longer straight (750-900m or so). Once you're up to or beyond ~4.8km (3.0mi), you want to look at having multiple long straights in all likelihood.
