Ultimately, I defer to your expertise on the issue, but your statement that it's 2x as much effort wasn't limited to the hardware aspects. I get what you're saying about having separate test teams, some duplication at the software level, and people to deal with regulatory crap, and I probably lowballed my 5% higher number, but I just can't see it being 100% higher. Maybe there's not as much shared as I thought, but is it true that there is zero shared?
