Scott, I keep count of the number of hits I make per a given area, knowing that I am smacking the weld area to remove distortion, increase the hardness/strength, reduce the weld bead volume, and reverse the weld-shrinkage. Accuracy is vital for this, both in targeting the hits and in keeping numberical count.
So many times I've arrived at the final leveling and filing pass to find a "loose" panel that quickly turns into an oil can.

So I keep the panel tight, all the way, with
frugal hammer blows. And the last leveling pass leaves it nice and flat and tight.
