My  questions are: does one determine FW strictly by (Stanwood)calculation?
What happens to leads that fall 'in between' where they should be? Do you
have to plug and redrill? I've heard mention of partial width leads being
replaced in empty holes where full width leads use to be. Logistically how
is this done? Does one cut leads to various standard widths(weights) to
test on the scale? I haven't done releading to this degree of accuracy yet,
but it almost seems like removal, plugging, and starting from scratch might
be a viable way to approach this.
