Correct me if Im wrong:
The pulses are reflections OFF THE INSIDE OF THE PLENUM, not the runners themselves. So you will have tiny little reflections, so you will get the benefit of those reflections no where in your rpm range. I dont know if pulses are a disadvantage at any point, I dont recall reading that anywhere.
Has anyone done any research into how the resonance frequencies of the intake manifold effect the flow? Its probably minor compared to things like volume, length, etc.

All the things you listed would affect resonance frequency, but so would the material its made from and a whole lot of other factors. Its probably not a big enough influence on power to justify the effort.

Does that set of dyno sheets reflect begi's NEW manifold that will probably never happen?
Last I heard that thing was supposed to be getting tested LAST SPRING. Nothing on there website even mentions it anymore. I'd love to get a manifold, especially one that is proven (see post 546). If I can find one I'll do a back to back stock 99 intake vs new and add more data.
