Which is already factored into the stats.

Well, of course you need to time your ascent such that you're going from Very Thin to Trace, you've already attained orbital velocity.

That is not going to work if the accelerate-to-orbital-velocity part takes 6 hours. Well, I guess it all depends on how high you jump...but yeah I really don't think that would work. :/

Why would I ever thrust
up? You can't fly a TAV
up unless it can do >1G. In fact, flying up is totally against the whole point of building a TAV.

You attain the velocity gradually as you leave the atmosphere gradually.
