You could run this in reverse as well, with switching from A+ | Richard's Calls

You could run this in reverse as well, with switching from A+ to A and the sells on A+ would move the price less and the corresponding buys on A would move the price more. In either case however, sellers outside the AMM can use their much larger supply that isn't in the AMM to discover the price as free markets do making the volatility less of an issue?
