Yes, they do.  Not "frantically" but seeming to pause near 1 spot or
another for brief periods.  And often I get 2 or more at the same time,
i.e. during the same pulse-burst.  That's surprising since I would have
thought that once the first one started, then all the energy would go
into that one.

Anyone have any light to shed on that?

Very likely.  I use 6" x 24" since that's the bulk-buy Landgren size.  A
number of people say the bigger the better in terms of making the spark
longer or fatter--but I don't see a whole lot of difference between the
smooth 6" x 24" and my prior 4" x 15" corrugated one.  My $190 may have
gone mostly for beauty.
