Is it possible to configure the cache/refresh duration of the variation we receive (currently it looks like its every 5 min which is a bit too quick) if not can this be added? Can we know if the variation is of an A/B test or a launch? (i.e. to know when the experiment is over and to no longer send the events to save bandwidth) Why is there a limit of one active test per project? this just force us to work in a project==test mode , a side question why does the implementation require the project name for both the variationset and to get the variation from the variationset isn't it redundant ? can there be more than 1 variation in a variationset of that project?
