You get a sense with the recall data asking for serial numbers between such and such a range. That’s my conjecture.History ? Based on what ? MR threads, even historically, you have no data on return/repair %. Hence I recommend we avoid such claims with no data.
I fail to see the logic , if not , than must be small ? Though I assume you mean within manafacturing process, in which case , yes small, unless some component is very difficult to deal with. But I agree , tolerances are in place to ship products that have small % of defects that are returned.
You know we are discussing a potential structural integrity design issue here, making it 100%.
Even the issue with the iPhone 6 wasn’t 100% because my son had one. It worked till he dropped it.
