Or, to do it all in one fell swoop from the shell...

You could do the same thing from within Vim by editing the file and doing...
:w !sed -n '3~6p' >test1.out
:w !sed -n '4~6p' >test2.out
.
.
In my opinion, these approaches are a bit simpler, but of course, they
work only if you have POSIX tools on your system...
Actually, this only works with GNU sed. The "~"-adressing is a specialty
that is not required by POSIX and I am not sure which other sed support
it.
Good point. Those without GNU versions of sed could use something like...
for i in 1 2 3 4; do sed -n "$((i+2)){:L;p;n;n;n;n;n;n;b L}" \
test.txt test$i.out; done
...or using awk...
gawk '/^-[[:space:]]*$/{getline; for (i=1; i<=4; i++) { getline; \
print > "test" i ".out" }}' test.txt
Neither as simple as the GNU version, but still arguably simpler than
the pure Vim approach...
