A different way to add filler (OA)

In another thread, someone suggested Elza's "Aircraft Welding" as
a good read. I got it from Lindsey Publications and am finding it very
helpful. There is a section in the back devoted to step-by-step
exercises in learning different OA procedures/welds. The book was
apparently designed for students in the Wichita school system who were
headed for welding jobs at the Boeing plant (1942).

One thing he says is counter to the 'dab the filler into the molten
steel puddle" school:
"The puddle is started as in the preceding exercise, and, after it
has been established, the end of the rod is applied to the front edge
of the puddle. ... The molten end should at all times be in contact
with the front edge of the puddle. In other words, the metal from the
rod should be continually flowing into the puddle rather than being
added in drops."

Pros/cons/comments? This method is certainly easier than dab,dab,dab. -
