8th order bandpass with LTC1562 and Total Q value

Hello,

I want to design 8th bandpass filter with LTC1562. I can calculate Q1..Q4 values from datasheet but I don't find total Q and bandwidth.

There is some quick design formulas for bandwidth=-3dB  & Q=10 on page 16 in datasheet but I need different Q ve BW values.

Please can you show me how I can calculate? 

thanks
