Basically has same characteristics as a regular [[SPAMAYL]], except the naps are longer on this one. The amount of naps needed also can be decreased compared to SPAMAYL with shorter naps, which makes this easier to schedule around the day. Also, similarly to Metaman and Metamaxion, SPAMAYL-40 is a bit more double for regular people. This schedule was suggested by many people, partially done by Sporky once, who mixed it with shorter naps too though. Longer naps had an architecture of mini-cores, often containing both SWS or REM or one of this stage being dominant. Sporky's average sleep cycle is close to 90 minutes on monophasic sleep, which either was compressed so much or used a wake time programming method to insert some light sleep at the end of the naps, which maked waking up easier. Similarly to the above mentioned schedules, SPAMAYL-40 doesn't allow for long uninterrupted SWS episodes, which likely is unhealthy for the glymphatic system process.

Taking any regular schedule with extended nap(-s), a new schedule of this category will be the result. An example includes [[DC1|DC1-modified]] on a picture near this paragraph, which has a 40-minute nap outside of the REM peak. The mechanism of this likely differs from the pronap-only schedules above, since the total sleep time is much higher and the compression levels are much lower. Also all needed SWS should easily be placed in the cores, which possibly will allow longer naps have little-to-no SWS, thus making them more refreshing initially. It is unclear if the wake time programming will be applicable in this case too, but this is worth experimenting. Longer naps on the regular polyphasic schedules might also compensate for a bit shortened cores (e.g. a DC1 variant with 3h + 1.5h cores, or a [[E2]] variant with a 4h core).

According to [https://academic.oup.com/sleep/article/19/9/707/2749902 this] research, the polyphasic sleep community has an established recommendation to leave at least 1.5h gaps between two blocks of sleep, preferably even longer (about 3 hours) to ensure brain doesn't count them as one interrupted block of sleep, decreasing their quality. It was found in the study that frequent awakenings followed by immediate returning back to sleep decrease sleep quality, leading to a higher percentage of light sleep. A known Zoidberg attempt has proven this statement, after two sleepers couldn't adapt to the schedule because of much lower sleep quality. But recently a new idea was suggested by some members of the polyphasic community. In fact, it's possible that the main reason of the reduced sleep quality on schedules with short gaps were not the gaps by themselves, but rather SWS interruption, or mid-cycle wakes in general. Therefore, a new mechanism was suggested - full cores with a short gap (30-60 minutes) in between. This makes getting long uninterrupted chunks of SWS possible, and likely will lead to a normal sleep structure (similar to a one with longer gaps between cores). Also it might be possible to have a few REM naps close to each other during the dawn hours, with each of them having a high quality.
