It's actually rocket science but anyway. Private voting would be fine to encourage everyone to participate but that won't make the draw fair or stop people from complaining.
But what happens now if a rocket is really really sick? I'd like to see a scientist do a rocket double bypass.
But Marto clearly stated making votes private 'Isn't Rocket surgery'. So I don't think it would make him better.
one shouldn't eat green meat. No kidding. It doesn't take a degree in rocket surgery to figure out something like that!
