It has more to do with peak exhaust temperature and exposure time to that temperature rather than simply hitting an A/F ratio and melting the cats.
As a point of reference a roadrace car may bake the cats after running several weekend track events, or a turbo car may bake the cat after one 1/4 run.
I think you would be hard pressed to do any damage to those cats at any A/F ratio if you are just using the car for occasional street fun.
