Rule <R11> "60 Inches" Max diameter?

[RobotRaider]

Rule <R11> clearly states that the Maximum Horizontal Dimensions of Playing Configuration are 60" (213.4 cm).

1.) These don't match. 213.4 cm is 84" give or take.
2.) ^^ that being said, :in 2007 there was a similar rule that stated Maximum Horizontal Dimensions of Playing Configuration: 80" (213.4 cm). Which actually makes sense.

I'm sure this will come up in Q&A tomorrow. Just wondering if anyone has input or knows something new about this and what the likely outcome is.
Let's hope that it is the same rule as before: 80" (213.4 cm)

Thanks!
