Hello,
Use Counters[0] as reported by the Telemetry Aggregator (via the HTTPS
API, and the aggregates dashboards on telemetry.mozilla.org) have been
over-reporting usage since bug 1204994[1] (about the middle of September,
2015). They are now fixed [2], and in the course of fixing it, :gfritzsche
prepared a nifty view [3] of them that performs the fix client-side.
Can you give a sense for the size of the error in observed counts? (Is
this a 15% should-have-been 10% type of thing, or almost always a
15.001% should-have-been 15% type of thing?)
Could you order all of the counts by percentage error and send out a
list of the top 10 or so? (eg in your blog post, you had
PROPERTY_FILL_DOCUMENT going from 10.00% -> 9.46%, for an error of
0.54%. If that 0.54% is in the top 10, report the measure with its old
and new percentages.) Really, it ought to be the list of measures, if
any, that crossed over some "decision threshold", but I'm assuming that
for the most part we don't have specific thresholds.
I'm just trying to get a baseline sense for how much I should care. :-)
Thanks,
Steve
