I did read that(several times now) and it doesnt show an example of someone in a rating that is 100%. Plus that sentence under the chart… Calculate 60% THEN add… Makes it pretty clear if you ask me.
It doesnt say anything about the .6 getting 60% that way.
It says very specifically to ADD THE TIME TO THE 60%. Not use it to get the 60%.
I read it the way you did at first too. It was only after reading it several times that it all made sense to me.
