On page 71 of the electricians guide it shows the correction factor equation (0.65 x 0.88 = 0.458) so how does he get 0.458........??? on my calculator get 0.572

When doing the calculation 16 / 0.65 x 0.88 = 28. if you use my answer 16 / 0.572 you get 27.9 = 28.

So is (0.458) a typo ??

Im new to cable correction factors and this is just confusing me.

Thanks guys.
