Calcedony Prep

Got the glass cooking for a cobalt calcedony.
I've been looking back at the various post notes for working this temperamental glass.
One thing Pete has pointed out is a tendency to lose the colloidal swirls of color due to the normal rotation of the pipe post-gather. His recommendation is a "slap gather". While this is a colorful adjective, I'm not quite sure what it means.
I'd like to have a good strategy for working the glass so I can best evaluate the cooking ingredients and make adjustments accordingly.

So, how does one perform a "slapped gather"?

-or does it take two?
