From Polyphasic Sleep Wiki
An adaptation to flexing is required, and one should only flex once they have gradually increased the flexing range over time once the sleeper is adapted to the schedule and all other flexed sleeps, and their sleep is stable. Flexing too much or too fast is likely to destabilize adaptation as well, which happened to some members of the polyphasic discord community.
