Corey, can I trouble you for a experiment design review? The structure is essentially the same as the 66 experiment that you reviewed in Bug 1521626. The only difference is the context; WR was off my default in 66 and it will be on by default for eligible users in 67. We'd like to hold back a group in order to measure and document WR performance. The population calculation for this study and the endpoints (described in Bug 1526041) are same as for 66. Based on our experience with the deployment for the 66 experiment I'll ask for the larger 5% sample that we ended up requiring in the last study.
