I'm surprised more people didn't comment on this. Is it because Magic Chalk is difficult to get? Or is it expensive? Or is it because people just don't care which chalk they use because they chalk carefully on every shot anyway?Concerning the "number of hits until miscue," Silver Cup was very similar to Master (flag and pre-flag) and Lava. However, the Magic Chalk was off the charts!!! That stuff really remains effective on the tip for a long time! Here's a summary of all of the data in this category:
chalk: average number of shots before miscue
Blue Diamond: 11
Silver Cup: 7
Magic Chalk: 29!!!
Again, if you chalk before every shot, this doesn't make much of a difference. However, if you forget to chalk, or don't like to chalk often, or don't chalk effectively, and if you miscue often, then Magic Chalk could make a big difference in your game (assuming the miscuing is not a result of poor or inconsistent technique, which is often the case).
PS: Honestly, I was shocked by how many off-center-hit shots I could hit without miscuing using the Magic Chalk. The other companies need to figure out what they are doing and do their best to copy (or improve upon) it!
