No problem.

You might want to post a link to this page on the OpenStreetMap subreddit.

The test is very detailed. 25-30 minutes is optimistic. 60 minutes is more realistic.

Also, the scale of the Performance factor on the last two pages has the opposite magnitude to the other scales (right = low). I realise this is the NASA-TLX standard, but you should draw attention to it (e.g. by bolding “High” and “Good” under each scale) because people who started the test with the expectation of half an hour may be under intense time pressure by the time those last two pages pop up.

Finally, there’s no way to go back and correct earlier answers.

Please post an update once you publish your findings. It will be interesting to read about how people do on this test.
