Subject: Question on EGTB generation theory

Author: Alvaro Jose Povoa Cardoso

I red some papers on EGTB generation.
They mention that once a position's value is final (it's number of unknown
children is zero) it (the value) can be propagated to the position's parents
(plus 1).
And if some or all of it's parent's value are also final (the number of their
children with an unknown value is zero) we recursively propagate it's value the
their parents and so on.
My question is if this step is absolutely necessary for the algorithm or on the
other hand is just a speed up.

Thanks in advance,
Alvaro Cardoso
