I believed it. Hrant (and Brian) didn't. So now there are 13 people that they can disbelieve. Of course, we still need to figure out how many sets of tires they are disbelieving. I believe the responses reinforce my contention that the survey is meaningless for the stated goal since they show people have different results with the same model car, tire and inflation pressure but do not give any indication as to the reason for the differences.If the goal were instead to figure out the reason for the differences, you're correct, we would need a lot more data - complete results on a number of variables from everyone, and probably a lot more responses than the 21 we've gotten, since we would then be "slicing and dicing" the data much thinner.
