That’s just it. If we knew how many catoed and how many total flew at a launch we’d have a better understanding.
You'd know rate vs. count. But you still wouldn't be able to compare rates unless you had the denominator of other motors as well.
You can still do comparisons, though. They have assumptions - but I think they can still be used with care.
Has the E12 reported CATO YTD (or month - pick a time frame) changed from historic levels. plot it like a control chart. Assumes usage hasn't changed significantly.
Does the E12 get a different number of reports than similar motors (like the D12)? (Assumes at least a constant ratio of usage rates, though I would go further and posit that more D12s are flown than E12s)
Data I'd love to see, but can't without inside Estes knowledge, is a list of all the E12 production lots. How many lots have reports? How many have none? In the past, when I've had a CATO, or checked the list, all the hobby shops around me have those same lots on the hangers, and they seem to stay there until they sell through.
