Maybe maybe maybe

And about 400,000 metric crap tons of luck.

Ya think 400,000 tones of luck. Maybe 200,000. But not 400,000. The dude obviously knew what he was doin other wise he would not have split the buildings.

Skill can't account for everything, just when you think you got a tree falling just where you want it a sudden wind gust pushes it the wrong way and you end up with a town wide blackout for 17 hours because you turned a pole mounted electrical transformer into a firecracker.

But I still think 400,000 is to much. I see your point. An you are correct. But when ya have skill you can take the surrounding into play. Yes you do have the shit that pops up unexpectedly. Like wind or an animal. But a lot of the job is dude to time an with time equals skills.
