Found it. The map says "12.7" not "27" but people read it wrong. The page says the artist added an extra 2km/s delta-V for gravity/drag losses when aiming for a colony in the upper atmosphere rather than the hell world surface.

So by living in a gravity well do you mean in the toxic gas clouds of venus or the dry frozen irradiated deserts of Mars where a system failure would be worse.

If the SHTF on a space colony at L5, with 4.1 km/s of delta V you can be back on Earth in 2 days. If you run out of repair patches for your Venusian balloon home, you're sorta screwed unless you've got a rocket with 16.2 km/s delta V and enough supplies for the long multimonth journey.

You're that same guy who thinks space colonies are technologically infeasible aren't you?
