It does make sense to me that there would be at least a month between publication of the full draft plan, including the documentation that requested, and the closure of the comment period.
In its current form the plan is too vague for me to support it as written.
I think that the WMF audit committee or the WMF Board might be in a better position than the FDC to do a thorough review of the plan, including holding public Hangout meetings in which the plan is discussed, much like how government legislative bodies review proposed budgets in public. This would increase public confidence in the quality of the plan.
