Last week we wrote about why we stopped reporting weekly performance deltas. A single week-on-week number was hiding what actually happened in between, so we replaced it with a 7-day score series and let the digest reason over the full week instead of two snapshots. That was a step in the right direction, but not the whole answer.

A single week-on-week number sounds precise. For PageSpeed in particular, the results over the week can vary hugely. Taking a single snapshot and deriving performance off the back of 2 values can be very missleading and misrepresent the actual situation.
