I've been biphasic sleeping quite happily for a couple of months now.
I've seen several studies on sleep (and like everything else they vary quite a bit), but none of them really cover the biphasic approach. For this reason I've found my own experimentation (with times etc) to be the most helpful, as well as reading of the experiences of others.
Zulu, to answer your original question, I've gone from around 7.5 hours to a steady 6. No massive change in quantity, though the quality is a lot better.
