Dogy, I was wondering the same, and that's why I'd really like to see an update & clarification. There was for sure an error with that intercept, on the NR.
They reported 62.07 to 67.28, and said a 0.21 interval ?
So, is it really a 5.21 interval, or should it have read 62.07 to 62.28 (not 67.28)??
That was the only math mistake I saw on the NR, but clarification & location are really needed!
