Yes and no. My original switch to biphasic sleep was a 30 day trial
(that article contains links to each of the individual days, as well as a summary), and I tried a 1.5/3 hr split a few times during that.
In the end, however, I settled into a 1.5/4.5 split which now (a little over two months later) feels great.
It's a personal thing, and definitely one for a bit of testing.
