Changes

The inner ring is the original variant of the schedule proposed by [[Polyphasic Society]], which cuts more sleep than the current standard variant. Totaling 4h40m of sleep, this version has a similar amount of total sleep to E3 (3.5-hour core). However, scheduling a 2.5h first core may result in heavy SWS wakes in the beginning and cause oversleeping. This reduced total sleep may also make this variant less flexible after adaptation. Throughout the years, this variant has seen little success, but those with slightly reduced monophasic sleep requirements may be able to adapt to it more easily.

It may also be possible to compress the cycle lengths down to 80 minutes. The common approach would be to adapt to the standard variant, and then wait for the compression to occur. It is not recommended to directly start an adaptation to variant.
