In enquiring to see if reductions of net sleep time can be achieved
using polyphasic sleep, prior assumptions need to be put aside for the
duration. The answer may or may not be yes or no (or no or yes or
zzzzz). But confirmation bias may well swamp a learning opportunity.
There is certainly much anecdotal and other material that suggests
that net sleeping hours reduction can be achieved. What if any effect
this has long term is TBD - and looking into it can also be heavily
affected by  presuppositions (which may or may not be valid).

FWIW, for me, taking VERY short naps (under 8 minutes eyes-shut to
eyes-open) as required makes a substantial difference to my general
state of mind / tiredness / ... . Certainly doesn't work for everyone.
Note - that makes no comment on my total sleep requirement.
