You're right. Up to a point. Your time frames are correct for an "Accepted" filing. Submission is not acceptance. If there are questions about the filed material the SEC will require explanation and/or clarification before acceptance. Although acceptance should be forthcoming, it may be (as HHSE blog states) a few days. Until a few days, at least, have past, I would give them then benefit of your doubts. Presumably you would want to be able to rely on the Form 10. Just as does the SEC.
I, as yourself, hope that "Acceptance" is prompt and publication is also.
Yea, HHSE.
