<pre>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 : <a href="https://gist.github.com/bcaudan/bfab026fa2416af9fc48dfacc4a59938">https://gist.github.com/bcaudan/bfab026fa2416af9fc48dfacc4a59938</a>
Do you have any news on this issue?</pre>
