Pageview analysis used to estimate expected pageview counts here.
Will need to continue with an estimate for month of July due to fix release schedule for apps.

@SNowick_WMF to update this task: what next steps were decided on (or proposed)? If work has been done on those next steps, link to relevant tickets or documentation.

@kzimmerman given that data , after rewrite, had significant issues until most recently when those were fixed I think it makes little sense to backfill. See: T256516: Re-process webrequests from 2020-05-18 so that page views from latest Wikipedia app releases are counted for examples of issues found.

@Nuria, just to clarify, we will not be requesting re-processing webrequests, this ticket is for my next steps to estimate pageviews for periods missing data and other related tasks.

• Write incident report, stored in Product Analytics shared drive 'Data Incident Reports"
• Documenting fix process in ticket (there were several different changes)
• Noting dates and app versions that were affected - for future data knowledge, how do we exclude/include where data was missing. Where can we put those to make sure they aren't lost?
• Estimating lost views and validating that fix is actually working (depends on new app version saturation) Estimated App Pageviews
• Who else needs that estimated data? CChen: Key product metrics, which goes into quarterly deck, publish key metrics on Commons. Also CChen for Superset. @cchen has estimated pageview counts
