So I stopped using the two base theory when DBS Chapter 13 came out then I wasn't for it anymore and now I'm to another point where I'm somewhere in between. So I'm back to my original thoughts of Saiyan beyond god. But it's not something Goku uses in the Universe 6 and 7 tournament, let me try and explain. So after Goku's battle with Beerus I don't think that Goku's base became equal to the Super Saiyan Red form but I do think that Goku absorbed the powers and became stronger but not to the point of Super Saiyan Red. He then found in Whis's training to tap into his old Super Saiyan Red powers by using Saiyan beyond god that he uses against Final Form Frieza and there is one manga panel that he is using it in training against Whis. The form is strong and is as powerful as Super Saiyan Red but doesn't have all of the benefits of it neither is it god ki. Goku at some point had however learned how to actually transform into his Super Saiyan Red form which had more benefits than that of Saiyan beyond god. So he was almost replacing Saiyan beyond god with Super Saiyan Red.
So here is a mini power scale of how things should be: SSB Goku>SSR Goku>=SBG Goku>SS3 Goku>SS2 Goku>SS Goku>Base Goku
So it isn't that I think that Saiyan beyond god is god ki, because it's not, but it's that I think that that was one way of tapping into the Super Saiyan Red powers. Hopefully what I'm thinking makes sense to you guys.
