says that there is no need to use the 2(D+1) dimensional strategy
- that Poincare section 2(D-1) search works better, is faster.
The Poincare section is computed using the Henon's trick as written up
in the "Maps" of the webbook.
In order to determine the
[2(D-1) x 2(D-1)] Poincare map stability matrix from the flow integration
compute 2D Jacobian as for flow, then find the change in time needed to
hit the Poincare section again, substitute back to remove one degree of
freedom.
The attached

makes above remarks concrete.
