 // Summary of all histograms Perceived PLT histograms:
 // (all prefixed PerceivedPLT)
 // PerceivedPLT -- Perceived Pageloadtimes (PPLT) for all pages in the group.
 // ...Windowed -- PPLT for pages in the 30s after a prerender is created.
 // ...Matched -- A prerendered page that was swapped in.  In the NoUse
 // and Control group cases, while nothing ever gets swapped in, we do keep
 // track of what would be prerendered and would be swapped in -- and those
 // cases are what is classified as Match for these groups.
-// ...MatchedComplete -- A prerendered page that was swapped in + a few
-// that were not swapped in so that the set of pages lines up more closely with
-// the control group.
 // ...FirstAfterMiss -- First page to finish loading after a prerender, which
 // is different from the page that was prerendered.
 // ...FirstAfterMissNonOverlapping -- Same as FirstAfterMiss, but only
 // triggering for the first page to finish after the prerender that also started
 // after the prerender started.
 // ...FirstAfterMissBoth -- pages meeting
 // FirstAfterMiss AND FirstAfterMissNonOverlapping
 // ...FirstAfterMissAnyOnly -- pages meeting
 // FirstAfterMiss but NOT FirstAfterMissNonOverlapping
 // ..FirstAfterMissNonOverlappingOnly -- pages meeting
