From Polyphasic Sleep Wiki
Note that pronaps on regular E3 is not recommended, as the 3 or 3.5h cores may not cover all SWS needs when adaptation first begins. Extending the first nap may increase the chance for a SWS wake, even if it is around REM peak. A Pronap is often used for individuals with high REM requirements (>100m).
