In the same way that Team Sonic's times are only counted once, and you can claim your best on either mission, why isn't the same done for Team Chaotix' Grand Metropolis, Frog Forest and Egg Fleet? All we're doing is wasting our time trying to achieve the same time again.
I would have brought up the topic of Chaotix rings too, but Rusty's talking about removing them completely (much to my delight), so no need for that.
