That is far too much rocket for a person asking this type of question in this way.
That is far too much snark for a person who thinks that "Amateur Professional" actually means anything.
To the best of my knowledge and recollection, and I'm pretty sure I'm right here, there is no such thing as "dynamic stability margin." If there were, and if it could be as easily interpreted the static margin, then we'd all be using it all the time. When you state that the dynamic stability margin is 3.25, to what exactly are you referring?
Dynamic stability is a complicated subject, with several different but interrelated figures of merit, and no simple answer for what constitutes a good design. To gain a better understanding of it, you might start with a series of articles that Tim Van Milligan wrote in Apogee's (that is, his) newsletter, starting with issue
192. Tim also covers the subject in his
book; that will give you the same information and may in fact be reprints of the newsletter articles. (Some of the book is put together that way, but I don't remember if the dynamics section is.) The book, obviously, has a lot of other good information as well; I'm not here to shill for Tim, but it is a book worth having on your shelf.
There are, of course, other sources for the same information. After you've perused one of them, please come back with a more specific question, if you still feel the need to.
