Solving tetration for base 0 < b < e^-e

The interesting thing is that \( g \) not only has the two attracting fixed points \( p_1 \) and \( p_2 \) but also a repelling fixed point in between. Which is attractive for \( g^{-1} \) in the range \( (p_1,p_2) \).

   
Graph for b=0.01 with p1=0.941482102273016 and p2=0.0130925205079953.

So why not do regular iteration at that inbetween fixed point?
