i don't doubt that. my points are:

a) there is nothing magical about zero crossings.

b) you might as well edit at any <arbitrary value> crossing. what helps
preventing clicks here is the fact that both sides of the splice are at
roughly the same value. what helps even more is for both splice sides to
cross <arbitrary value> in the same direction (unlike in my example,
which was intentionally nasty in that regard).

c) splices at similar values (or zero crossings, for that matter) are
not a 100% guarantee the edit will be clean.
