<p>thank you for the challenge, I had fun doing it ;-)<o:p></o:p></p>
<p>As MapRoulette adds the URL of the challenge to the comment of any changeset (given the mapper doesn't remove it), it is possible to request all the CSs using OsmCha's API:<o:p></o:p></p>
<p>curl -X GET <a href="https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fosmcha.org%2Fapi%2Fv1%2Fchangesets%2F%3Fcomment%3Dhttps%253A%252F%252Fmaproulette.org%252Fbrowse%252Fchallenges%252F37289%26page_size%3D10000&data=05%7C01%7Cmarjan.vandekauter%40tomtom.com%7Cb56ab352004246c3599d08dafe41af32%7C374f80267b544a3ab87d328fa26ec10d%7C0%7C0%7C638101855322234453%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=O%2B%2BL5%2BXnz1IFZxCZ2ZcI%2FyzvFLXHNpLo55mzDE5OIC0%3D&reserved=0">
"https://osmcha.org/api/v1/changesets/?comment=https%3A%2F%2Fmaproulette.org%2Fbrowse%2Fchallenges%2F37289&page_size=10000"</a> -H "accept: application/json" -H "Authorization: Token <<REDACTED>>"<o:p></o:p></p>
<p>will give you a json with all 56 CSs that contain the comment. As you said there were 88 cases and 64 cases where fixed, it's reasonable to assume that either 8 changes where fixed within one CS or someone removed the comment - but you've got 87,5% of changes
available for you to analyze.<o:p></o:p></p>
<p>The Authorization Token, redacted here, can be retrieved when you're logged into OsmCha.org, click on your username, go to Account settings and copy the API key.<o:p></o:p></p>
<p>I have attached the result of the request for convenience.<o:p></o:p></p>
