[17:05:08] <slangasek> but what you could do is tack an install-date into the submission data
[17:05:34] <slangasek> you could then retroactively include that machine in the stats for every day since it was installed
[17:05:49] <slangasek> (the math would be fierce though, left as an exercise yadda)
[17:07:56] <slangasek> again that's a retroactive calculation, so it doesn't keep the spike from appearing at release time but it will make it disappear after the fact when recalculated
