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.
Hmm.. Didnt know that but the logic is good.
