Thank you very much for expressing exactly what my concern was.

So now you should also see why it's ludicrous to expect that Venus has meandered around the solar system.

Sauce for the goose.

Origin of the Earth and Moon

Moon making made easy

More computer power will help, but the problem will remain that giant impacts are inherently improbable, and the Solar System's chaotic nature makes it impossible to re-run history and get the same outcome. "None of the scenarios for the Moon's formation is highly likely," Stevenson says.

That does not indicate what I believe about either scenario, it just means I don't think ludicrous applies.
