Hello -

We have Champion at 50% allocation and remaining allocated to Challenger. When the report is taken from Interaction History, the challenger is getting allocated more than 53% where as Champion is down at 47%. For a four week run the distribution was steady on first week and 2nd week onwards it started tilting towards Challenger.

I wonder why there is such a big statistical difference in distribution considering Champion challenger component is supposed to be random distribution based on  configuration and not having any intelligence around user preference.

We are using Pega CDH 8.4
