LN hasn't sold anywhere close to 10,000 replacement bearings. Sure, maybe some people part out the car rather than repair it but then you also have to take into account that some large percentage of LN bearing sales go to cars that have never had a bearing failure in the first place (preventative replacement). Other owners might find a salvage engine from a car that was totaled in an accident but there aren't 10,000 of those either. And last, if the numbers were that high then the aftermarket/eBay would also be flooded with failed engine Boxsters and we just don't see any of this happening.
The only conclusion is that the engine failure rate is much less then 5% (or failed Boxsters are with all of the socks that disappear from the dryer).

If I recall, LN estimated 20%+ failure rate. You aren't accounting for cars that got new engines through Porsche, rebuilt with the stock IMS (which was the only option before LN, and the cars that were just junked or parted out). At this point, many Boxsters aren't worth fixing if the engine fails. Sad, but true.
