I haven't checked your multiplication, but I'm sure that it's fine. The underlying assumptions less so.
Here's what the SEC wants:
"In order to bring your filings current, please file your Form 10-Ks for the years 1997 through 2009, including audited financial statements as soon as possible."
I've been through it before, but don't remember where I ended up regarding the quarterlies. They absolutely AREN'T required for every year since 1997. They absolutely ARE required for 2010 (plus Q1 and soon Q2 for 2011) and PROBABLY for 2009. (Note that there are only 3 10Q's a year, not 4 as your post suggests). So in all likelihood they would need to prepare 3(2009) + 3(2010) + 2(2011) or 8 10Q's to catch up. From an investing standpoint, the last 2 are probably the only ones that matter.
The quoted SEC statement was made before the 2010 10K was due, so there are 14 10K's due as of now. The activity levels in a number of those years appears to have been negligible. And the OMB estimates are heavily weighted to large cap stocks where operations and financial functions are far more complicated than they are here, so they are ALMOST irrelevant.
The only thing we really know is that catching up will require significant effort, money and, judging by the total lack of results to date, a lot of time.
