The rule gives you two possible diameters that your robot must stay within, 60" or 213.4 cm. I know which one we're using.

Seriously, I have a strong hunch the correction will turn out to be 84". Looking at the table, it is easy to imagine how the 60" could have been a typo, mixed up with the 60" in the starting height box. How likely is it that you would accidentally pull the number 213.4 out of the air as a typo?
