Yeah, I understand that, but using any kind of numbers to try to approximate one's chances of failure is not helpful in absence of actual numbers. You probably think 5 reported failures is low, but some people get all out of whack when there are 8 reported iPhone 8s coming apart without even thinking about the total sold quantity of 15 million. Even then it's pretty meaningless because for an owner who needs warranty service, their failure rate is 100%. My suggestion is not even go there and keep the discussion to what are the best options in case of failures or if there is evidence of a design flaw, then let's start talking numbers.
If people want to see more of this for entertainment value and drama, just visit a Chord thread, especially the Hugo 2 that recently launched. There you have the Chord representatives actually accusing customers of nit picking and outright lying, all the while forgetting about the case fiasco of the Hugo 1 V1.
