From Polyphasic Sleep Wiki
Nap spacing should account for natural periods of tiredness. In the evening 6-7 hour gaps are common, whereas gaps in the morning tend to be shorter. A pronap may be used during the REM peak (6-9am) to gain extra time in REM sleep, allowing larger gaps and/or more flexibiliity later in the day.
