I used the following curl command on 1000 client_ids to check A/B traffic using traffic_fraction as 0.5 but got unexpected result which was skewed distribution of red and blue alternatives. I got red around 250 and blue around 750. Can you look into this bug.

curl "http://localhost:5000/participate?experiment=myexperiment&alternatives=red&alternatives=blue&client_id=<provided 1000 client_ids>&traffic_fraction=0.50"
