Help with speaker placement in my real life room

Hello all, I just set up a pair of Wilson Sophia 2's in my living room.  They are on wheels at the moment so I can tweak the position.  Can you give me a bit of advice on placement with the limitations of my room? I tried the Wilson Audio Setup Procedure, but as I was on my own, it was very challenging.  I plan to do this again when I have a helper.  I then went the route of getting the speakers as far as I could from the back wall, and varied distance between speakers and toe-in degrees.

What I settled on for now is sounding very good, but perhaps still not perfect, hard to say. The thing is, the triangle is far from equilateral, as you can see from my drawing. I tried to get it close to equilateral, but that would require the right speaker being very close to the side wall. When I did this, it sounded far worse. Do you think this is ok, or by the book, to have a listening distance to speaker distance ratio like the drawing is indicating? I want to know of there is some rule that I am missing that may be holding me back.

The right speaker’s tweeter is 51” from the back wall, and 37” from the side wall

Here is a link to my updated schematic drawing of my room and speaker placement.
