David, I understand your points about both the lack of data and the lack of context to put it in. But I have serious doubts that any changes to -force- clubs or manufacturers to take on additional reporting burden and/or reveal commercially sensitive data are forthcoming [for a hobby product that nearly never leads to fatalities].
A scan of rocketreviews.com flight logs does reveal a little more context. At least people report both good flights and bad. It is a small number of fliers, but it's openly accessible. The motor search page shows the most recent 100 records - so you can even get an idea of how popular motors are by looking at how far back it takes to get to 100, if it even get there.
For instance,
E9 - 8 CATO / 118 records (clusters added in) since 4/2014, 100/27months
E12 - 3/43 since 6/2012, 43/49 months
A10T - 2/100ish since 5/2014, 100/26 months
C11 - 1/100ish since 9/2013, 100/34 months
A3T (64 months), A8 (11 months), B6 (10 months), C6 (9 months), D12 (10 months) - 0/100ish - each
E16 - 0/6 since 5/2015 6/14 months
F15 - 0/10 since 5/2015 10/15 months
And for comparison -
AT D15, 3 CATOS, 9 delay failures /100ish, 168 months.
AT F39, 0 catoes, 2 delay failures /100ish, 84 months
Only 1 CATO report in rocketreviews listed the lot number, though a couple noted they were anticipated CATOs, flying from know bad lots. I must have found aerostadt's list previously.
It occurs to me that if one wants to generate a better, and end user generated, data set, then one needs a killer app that _happens_ to collect the data while providing tools/services the end users want. Rocketreviews is a start - at least people log both good and bad flights. If they listed lot numbers it would be better. If the app could automatically send the MESS report, it would mean one stop data entry, and could prompt for missing info to help mistake proof the process.
To recap, the known problem lot numbers in the thread:
