That is truly a interesting point of view!

What is the criteria for a poll to have "meaning" to you? Please note this was a poll conducted by a highly regarded Porsche site with nearly 800 Porsche owners expressing their experience with presumptively no shenanigans in play. Although no poll shows precise accuracy, I do believe the results would not be so far off to negate the validity of my opinion.

A poll on an internet forum for a specific car is fundamentally not representative of the population as a whole. People tend to go to car forums to find solutions to a problem; while not all of those problems are going to be IMS bearings, some of them are. You wouldn't assume that a poll of 1,000 people on an alcoholics anonymous site is reflective of the drinking habits of the entire population.
A sample size of 800 in an overall population of 175,000 is tiny; less than one half of one percent. While there are certainly plenty of studies based on a small sampling of a very large population, it's not realistic to think that Rennlist members are representative of the population as a whole. This is a technical forum; a place where people come for answers to problems. I think you'll agree that you are much less likely to go online and join a forum for a product that works perfectly and for which you have absolutely no questions or complaints.
It's also worth pointing out that the definition of IMS failure has changed over time. Today, a speck of IMS material in your filter is now considered a failure; in the past, IMSB failure meant a crumpled intermediate shaft and a few quarts of oil on the street.
We have to base our decisions on something; the information available here is far better than nothing at all. However, what we have here is fundamentally subjective; it's not "data." MAYBE if you squint at it you could rationalize calling it data-ish...but that's a stretch.

Yeah, we turned this thread into an IMSB thread.
Ooh, what have I learned since joining Rennlist?
869. All threads in the 996 forum are IMSB threads just waitin' to happen.

A sample size of 800 in an overall population of 175,000 is statistically insignificant - less than one half of one percent. Those 800 people are very likely NOT representative of the entire population for the reason I explained above - but even if they are, the margin of error for a loosely-defined poll like this eclipses any statistical data you can derive from the small sample size.

Considering your explanation, would my opinion that is based on "Some Validly of data" be considered over an opposing view based on "No produced data"?
