Brian, that is a fantastic site that you maintain, by the way. I've used those engine tests to help me select props for use, especially where I don't have manufacturer instructions. Also they've helped to substantiate my observations, help others with prop selection on older engines, in some cases rebut bad opinions and bad advisement.
For example, I've found that the plain bearing sport Enyas, hold up well to the modern plain bearing sport Schneurle engines, if properly propped. Besides, I really like the writing style of Peter Chinn. He is thorough and pulls no punches.
