It would be interesting to know how the antenna would have performed without
feedline distortion by using with a choke-balun, however you did the test
correctly following the manufacture's instructions.
 
 
 My educated guess is that the primary effects of a serious common mode 
choke would be to prevent the nulls from being filled in by common mode 
coupling from  the transmission line. I would not expect to see the 
forward gain affected.
