Dear Paul，

    In cado-nfs2.2,you used method from your paper "better polynomial", where for different skewness, there exist many plolynomials. I obtain new polynomials by one polynomial subtracting another one and  then select the one with smaller leading coefficient.   usually these new polynomials will have smaller lognorm.

   I just use version 2.2 and the command is cado.py N workdire

   Best regards,

Meng
