--- Comment #6 from Bastien Caudan <bastien at content-square.fr> ---
It seems that we have this particular issue with our a/b test algorithm. We have this kind of repartition between test versions on safari:
Version 0:    800 
Version 1: 11 000  
Version 2: 35 000 
Version 3: 24 000 

We observe this behavior with all safari versions with significant traffic: 9.x, 8.0, 7.0, 6.1.6
However, Safari 4.0 does not seem to have this issue. 

We have reproduced this behavior on all safari versions available on saucelabs with this piece of code : https://gist.github.com/bcaudan/bfab026fa2416af9fc48dfacc4a59938

Do you have any news on this issue?
