Research:Editor milestones/Lifecycle

Questions

All of these editors made their 1,000th article edit in the same few months. Of editors who began contributing in the past 4 years (2008 and later), what do their editing velocities look like? (E.g., slow and steady, rapid and condensed?)
(Optional) How different is the velocity of editors who began contributing before 2008?
What is the typical/average velocity? What do the outliers look like?
What does the velocity of editors who made their 100th edit to articles look like in comparison?
What are the most useful temporal metrics for defining an editing session? (1 hour of inactivity? more/less?)
What does a typical editing session look like...

Include the following stats for each time period:

Generate a CSV that has each editor and their edit counts per time bucket and lifetime edit count.

E.g.:

User	0-1	1-2	2-6	6-12	12-24	24-48	48-168	Lifetime	# of sessions

We can use a simple definition of "count the number of >=1 hour gaps within the first 7 days".
Assumption: if a user stops for >=1 hour, they've restarted an editing session (e.g., went away for a cup of coffee, switched contexts, etc.).
The industry standard measurement for an internet session is 30 minutes of inactivity (e.g., that's what comScore uses to identify sessions). But since editing activity is a very time-intensive thing, 1 hour feels more appropriate.
Example: if a user makes 3 edits from 1:00-1:15, and their next edit is at 3:00, there's a gap between the first and second clusters. So # gaps + 1 would equal number of sessions.
