And the OP didn’t mention any wind, which I expect they would have were there any, since you can’t account for it if you don’t know (a) that it exists and (b) which direction it’s coming from.
Probably because they were using different figures for the height of the building. Not all stories are created equal.
I was ambiguous on wind, and other factors, b/c Well, I’m a bio major, don’t know too much about them math stuff. But the assumption is that sure there’s wind, but not enough to make a big difference.
And no, there’s no vacuum, that would blow way too hard 
Further, I doubt jumping off makes a difference, it only would matter to how far out you go, I think? The V0 at leap is the same, because the manbomb creates a organic quadratic equation 
I expect some jumpers might actually leap upwards a bit while departing the roof, so that would need to be calculated. And if the manbomb leans forward until toppling, that would also slow the acceleration for several early moments.
I imagine you would make these measurements from the center of gravity of the manbomb. The body would rotate around the center of gravity as it leveled, though the actual impact point would probably not be at exactly that height.
It’s even possible clothing would add another variable – parachute pants, for example. 
Vaccuums don’t blow. They suck!
Nope, vacuums blow, because the observed behavior of them “sucking” is actually because there is a depressurization of the opposite side. With the less air pushing up against the barrier in between, the higher pressure pushes in the opposite direction. I hope I’m being clear when I write, but then again, I probably don’t know what I’m talking about either
Well, your calcs in post #2 yield a final velocity around 196 ft/sec (= 133 mph). This is a bit more than terminal velocity for a skydiver in a stable belly-down position - so the force on a body at that speed is approximately equal to its weight, which I’d submit is more than a negligible effect.
113 mph or 120 mph±13? hehe
Pressure pushes, vaccuum sucks.
Maybe that’s wrong. Pressure presses, vaccuums do not press back. So while vaccuums may not suck, they certainly don’t blow.
I found this freefall calculator which claims that a 72-kg man falling 601 ft through air will take about 10% longer to hit the ground than he would in a vacuum.
10% longer would mean that he should jump when she’s 26.6 feet away. If your freefall calculator is correct, that would not be a completely negligible difference.
Of course, I’m sure he can aim in flight, too.
You can? I assumed that pretty after you fall, you go straight down, accelerating at the same time. Until you reach terminal velocity, that is. So how does one go about doing this aerial acrobatics? Suggestions?
And, as I originally forgot in the OP, would manbombing, make a good first impression? And when do I deploy the parachutes, gotta make this safe
Okay, relatively safe…
It would certainly make a striking one.

As a skydiver’s speed increases, so does maneuverability. It’s obviously best at terminal velocity, but at even half that there’s some control. (In rough terms, maneuverability is proportional to speed squared.)
So if she tried to jump out of the way, you can correct? would there be enough time?
Unfortunately, her maneuverability will be much better than yours.
Let’s be honest, though, how many of us scan the air above our heads for falling men as we walk past 40-story buildings?
