Don't like it. Everything/course can't be "pigeon-holed" into some few guys loony 'color-coded' system broken down by an arbitrary number of shots based on a statistically-flawed rating system. Besides that's what an SSA is/was supposed to do (provide a 'hardness factor' for a course).
My understanding is that it's
not what the SSA was supposed to do.
It's a potential side-benefit, for courses where the tournament layout is essentially the same as the everyday layout.
The purpose of the ratings system is to separate Ams by approximate skill level. The SSA measures the course for a particular round and conditions, as a step in that process.
My understanding of the color-coded skill-level concept is that it's based on a course being designed for players of a particular skill level, not a course producing a certain SSA.
Of the 3 courses I play most, the SSA is only reliable for one (and a little shaky there):
* The one course is the same for tournaments and casual play, and SSAs very consistent from event to event, though the last singles tournament was April 2016 and there aren't likely to be any more anytime soon, so the SSAs will get stale as the course undergoes changes.
* Another course adds 2 temp holes, and a ton of O.B., for tournaments, so its SSAs aren't applicable to the day-to-day course.
* The third has a wide range of pin placements and extra holes used in tournaments, so SSA is meaningless unless you know where the baskets were, and which holes were used, for that round.
Which is why SSA would be useful, as a guide to difficulty, only if it were entered by someone knowledgeable enough to know that the tournament layout is what a visitor would see on an everyday basis. And that it was produced in normal weather conditions. Even then, it's not a precise number, but if you look at a course with an SSA of 62, and another with one of 47, you'd recognize the difference.
