This is exactly what I was talking about. If you get such data from every year, and look at the number of connectors that failed each year, then it's logical to draw a conclusion like you did. However, if you only look at one single point of data, then there's no correlation to be seen, as a single point of data never correlates with anything and never bears any significance.
I agree.
So why is your conclusion that the data won't change and age has no relevance? Your hypothesis was that since these are percentages, the 8pin is actually currently the worse product, when in actuality, when taking into account age, the 12vhpwr connector is the worse product.
Like the post in post #7 and the discussion which follows it, your hypothesis is essentially that age has no relevance, the data is meaningless, no conclusions can be drawn, and if anything, the 8pin is currently the worse product. You and them throw out age as a relevant factor and then come to an illogical conclusion. This thread is about age and product maturity. It's in the title.
The OP's hypothesis is that given the age and lack of product maturity, reaching failure percentage parity at such a young age is a bad sign. It matches expectations given the lower product safety factor, so it is not a surprise, but does confirm that there isn't some redeeming factor that we forgot to consider. I agree.
