Conventional wisdom would say that you never down or up sample in one go.

I have always avocated restricting sampling to no more than 50% in each step.

20mb > 11mb > 5.5mb > 3mb > 1.7mb > 1mb

You give the algorithm less of a challenge in deciding what to dump or dither.

It might be tedious doing this manually but I have a CS Action that does this sequentially in a few seconds.
