How reliable old download statistics? I just ran the extension download statistics, for all extensions, and why I sort them grand total, I am a little surprised with the some of the top results, such as SlicerXNAT, which I believe is not even maintained.
I don’t think it is necessary to distinguish download count obtained from the web browser or from the extensions manager. When someone downloads a package via the web browser, the intent is most likely to install it in Slicer.
This does not count as a download. Only extension package downloads are counted.
The numbers look good to me, I don’t see any reason to doubt their accuracy.
Slicer has a long history, so if a more recently added extension needs to be compared with older ones then you may consider limiting your analysis range to releases from the past few years.
@muratmaga you just spent a week with a bunch of users at the workshop, did you happen to get a sense of how they would feel about the question of sharing anonymous usage statistics? If not, could we reach out to them and ask?
