How much capacity do flooded golf cart batteries start out with?

Some time ago, I read an article that suggested de-rating your amphrs when you programmed your BM for new batteries. As I remember, they proposed derating about 20% initially, and then adding 5%-10% additional re-rating each year thereafter as a way to ensure the BM showed a reasonable value as a SOC as your battery bank ages. I've looked, but can not find that article....does anyone else remember-or do(?)-that?
