In my experience, working out in the 90-100% range is Evil Magic. It works for a while so you think "Hooray, I'm stronger than I've ever been" and you enjoy posting heroic numbers. Then it stops working and becomes all about demonstrating strength rather than building it. It sounds a lot like you've reinvented bodybuilding with your protocol. You're probably not actually stronger in a strict 1RM sense than you were before, but you may well be healthier and you sound happy, so why worry? If you occasionally threw in a peaking protocol and worked your way back up to the 90% range you'd probably be beastly; the trick is not to stay there.
