What? 3+stops? No. Why is there consensus that between 1.3-1.7 is the standard filter factor for circular polarizers? TTL metering automatically compensates and it ain't 3 stops or more. Dialing in 1.3-1.7 stops more exposure on a incident meter works for me, too. If you couple two polarizers together, it is possible to get a variable ND filter effect by rotating one. Not sure what you're advising makes much sense practically.
