Here's my take on it. It's not about pre-flag vs. post-flag. They are probably same formulation as skip from tweeten confirms it.
However, as the chalk gets older, it tends to get drier. The drier the chalk gets, fine particulates will crack into finer ones at a very small scale, and this will result in a more even and smooth coating when you chalk the tip.
This creates the illusion that pre-flag was a different formulation than the post-flag. I think old Masters coats similar to Blue Diamond, and there is certainly a difference between Blue Diamond/pre-flag and the newer post-flag Masters.
Very creative explaintion.
Unfortunately, that's exactly what it is. An "explaination" that was created.
The cold hard fact is: it has nothing to do with being 'finer'.
The technical term would be particle size. If it were actually about particle size,
we would all be chalking up with grandma's face powder, or baby powder.
Drier is better, usually, but if it were only about being drier, there are
several readily available home appliances that are fully capable of
making chalk as dry as any part of the Sahara you might care to choose.
The alleged different formulation may be an illusion, but the performance
isn't. Perhaps something was changed in the process??
I don't have any problem getting newer Masters to "coat" well.
My supply of Masters Blue was acquired WAY pre-Flag, circa 1991.
I'm not a champion, just like I'm not an Analytical Chemist. But I play
well enough to tell the difference. Granted, on a dry day, with the heat on,
maybe not all that much. But, on a hot, humid August night, or a rainy
day, the difference is serious.
