This is an investigation task for the request below.
Banner history/central notice -- sequence test (We talked about this last year but not sure if it is in phabricator. We can currently show a large banner on the 1st impression and then small banners on later impressions. We’d like to test more variations (one ex. Large banner on imp 1, medium banner on imp 2, small banner on imp 3.) We talked about mixins or adding more buckets for this. It would be good to find the simplest way to test this since we don’t know all the options we’ll want to try yet & how it will perform. Maybe adding 2 more buckets for a first test would be the easiest way to help us get an idea?)
