Yep, derating all taken into account, which is why I ended up with 5 conduits.

One thing I didn't take into account and I'm not sure about is ambient temperature correction factors. Not sure how...

Am I missing something here? If the existing circuit is ran with 12/2, why are you saying that you will run 4 #10? It's a 220 volt circuit so you would only need 2 hots and a ground.

Unless you...

In what scenario would you run two entirely separate circuits to a duplex receptacle? Why not just feed it with a MWBC and keep the neutral tab intact?
