Hey Atheory:
A couple of observations on this thread...
(1.) If you want folks to provide you feedback - you may wish to re frame from the use of "peanut gallery" to describe them?
(2.) Do the hard work upfront yourself - flesh out the OOBs, unit strengths, reinforcement schedules, objectives, etc. Get a working and playable scenario developed. Then send out requests for play testers. Gather players' feedback and comments after folks have played a few test games with your design. Don't expect folks to do your research for you.
For example - Your asking players to comment on your proposed reinforcement schedule. Without an individual doing extensive research on the D-Day OOBs and weighing the 'actual' versus 'potential' arrival dates of various units, looking at factors such as number of transport available to a unit, delays associated with enemy air interdiction, marshaling areas for the units, etc. - how the heck would anyone know that answer?
Again, IMO you are approaching this scenario development from the "wrong side" and you may wish to re-consider your approach here.
