The whole humidity issue and the fact that tests were done on different days was the main issue I had with Dr. Dave's testing... MC and Silver Cup were done on a different day than the others... Humidity and other variables will change the friction properties of the chalk, balls, cloth and tip... Without controlling environmental variables I do not think the test results are accurate.
I also have looked at the sound wave forms of the video and while Dave could not detect slippage prior to misscue there were peaks on shots where the ball looked to not take all of the english that should have been imparted that indicate there was some slippage occuring or maybe one side of the tip had a hard spot or glue layer exposed...
Dave later redid the tests again on a different day and MC was down at 17 before misscue... He has rewritten the chalk section on his site several times since the first version and even retested the MC AGAIN after bias was established from having posted results...
I don't think Dave would ever consciously skew the data but I think after the initial results bias sets in. Bias can affect confidence and since stroke quality is also a factor even unconsciously it could have had an effect.. I would love to see someone without bias try the same test and publish the results.....
Based on use and microscopic examinations I am very interested and yes I manufacture and sell the Great White chalk so I do have bias even tho we were not in the test group so I cannot do the tests without skepticism being involved....
I would like to see Silver Cup, Master, Triangle, NIB, LAVA, Blue Diamond, Magic Chalk, NIR, Balabushka, Kamui .98 and Kamui 1.21 and our Great White put thru the paces.... You might even want to do Green Master AND Blue Master and throw in a piece of pre-flag...

Well my test wasn't controlled or scientific in the least. I admitted that from the outset. All I know is I could never do with Blue Diamond what I was able to do with MC. I plan on trying out some of your stuff too Chris. And when I do I'll review it as well. I love your Accu-Rack templates and I should be getting a soft Ki-Tech soon from JP for a cube of magic chalk. Maybe with the Ki-Tech I can do a side by side comparison of MC and Great White?
