GP Power Tools incorporates a feedback survey which it will prompt an administrator user 30 days after a new installation or 2 days after an updated installation.
The history behind the survey goes back to the Support Debugging Tool days. The SDT did not have any registration system and downloads were not being tracked, so it was an attempt to get usage data and product feedback to help justify the continued development of the tool.
Anyhow, one of the questions asks for a score between 1 and 9 for Documentation and a number of respondents have given a low score over the years.
