The extracted chroma values are normalized by the number of freq bins corresponding to each chroma bin. This is done so that the chroma values are not biased the spectral window size

<First up, the second line isn't clear to me>
Also, shouldn't such a normalization be done at the end after the 2-D chroma array(12,X dimensions)is compiled to 1D(12)
Taking an instance when the window size - 512. There are 10 frequency elements in the Ab chroma bin, but the Chroma[8] value is divided by 3 though it is in Ab. Also chroma[20] is divided by 4 though it is in Ab as well. Please clarify why these differences occur.
