If we could simply push that over the finish line, then the only work remaining would be on the website. We could simply put the UA into the variation param, and identify a sample with the experiment param. Then, if the experiment justifies it, we can add more attribution params.

If we could push that over the finish line, then the work remaining would be on the website. We could put the UA into the variation param, and identify a sample with the experiment param. Then, if the experiment justifies it, we can add more attribution params in the same manner.

Ref: https://github.com/mozilla-services/stubattribution/pull/95/files#diff-253081adbe418770bdbe47b1f11c8320R62 We could ask :oremj if bumping it to 600 is possible, and then we could trim UA at 200.
