Yes, and yes. However, you really ought to lower your CYA level, particularly because the common CYA tests will report any level above 100 as if it was 100. So your actual CYA level could be far higher than 100.
It all depends on the CYA level. With CYA around 100, an FC of 12 is a far lower active chlorine level than you would see in the typical indoor pool (because the CYA has most of the chlorine bound up and inactive at any given moment). If CYA was zero then an FC of 12 would be a serious problem and getting into the range where you could damage the pool as well as the people.
Briefly, CYA that is too low means you will need huge amounts of chlorine to maintain any chlorine in the water at all. CYA that is too high means you will have a very rough time shocking the pool should you ever get algae. Somewhere in the middle is the CYA is just right level (30 to 50 for most pools). There are several additional problems/challenges when CYA is 100+ that are too complex to go into here.
Running a poll won't tell you the best CYA level for your pool. Just the average of what lots of different people happen to do, which isn't even close to the same thing. The truly ideal CYA level varies depending on several factors, SWG or not, amount of sunlight on the water, etc.
