Being that I'm currently studying psychology, I have one major issue with the study. It says (on page 14) that results were tested on different lane surfaces using a different type of oil. But only a few parameters were tested, this does not mean that statistically everything else will remain the same across different the different surfaces. Some surfaces and finishes will clearly be stickyer (not sure if this is the right word but i hope you understand what i mean) in combination. According to everything i've been taught a scientific study can assume nothing and must prove (using raw data) everything that is to be concluded.
The thing i disagree with is that the numbers don't decrease in a linear fashion across the board. They decrease in differing amounts, tho it is true that the numbers all decrease. Also the intended angle of trajectory at 49 and 60 feet is different, although still half is not numerically the same difference. I'd be interested to see what the differences across the other statistical measures would equate to.
Just some thoughts probably from a more statistical background and perspective than any of you cared to know. But hey, i guess we're all entitled to our 2 cents.
