I'm inclined to go with option #3, but I'd want at least ONE verify.
I don't know how many VERIFY marks are needed, but I'd suggest something like
this: If 10 verify marks are needed currently, then drop that requirement by
one per week, so that at 10 weeks, only 1 verify would be needed.
That way, anything people think is important can go out fairly quickly, while
still giving ample time to those who care to try it out first.
I think 6 weeks is a tad short, I'd go more like 2-2.5 months, but 6 weeks
would work.
