From Polyphasic Sleep Wiki
Generally, variants with a longer first core allows for more alertness during core gap, and the second core does not need to be as long. However, the longer the first core, the less "DC-like" it becomes, meaning that the sleep stages becomes less distinctly allocated into the two cores. The longer first core may also resemble Siesta, with the second sleep looking like a daytime core sleep.
