Is it just me.........It seems that, no matter when/where, the available chalk on the table always ends up being situated in a cluster on the table ledges. I constantly attempt to spread it around when shooting but to no apparent effect. All the chalk always ends up in the same place after a seemingly short period of table time. I have relegated this to another one of those weird, unexplained phenomena, sorta of like dog/wife behavior. Anyone have any empirical data??
