That is some great data Squint! would you care to offer a bit more "discussion" or "analysis of the data to share your interpretation?
From what I can tell, when you say "Severe rolling" you are saying that this particular pedal allows the cleat/shoe to rock significantly side to side, correct?
That is surprising and interesting to me that this occurs in the case of Pedal C, which has only lost .04mm off of the medial and lateral sides. I would not have guessed that such a small amount of wear would make that big a difference.
Was your assessment of the severity of rolling/rocking made with brand new or used cleats? I am assuming you used the same cleats at the same point in time to assess all 3 pedals, but please correct me if I am wrong.
How would you describe the rolling/rocking of pedal A, for example is it nonexistent, or noticeable but acceptable?
I am asking the above questions, because I am curious how cleat wear fits into this.
Slightly off topic, it would be cool if we could more easily measure the actual number of degrees of rocking. It wouldn't be too complex to do, but would require a bit of fabrication.
