The SEC will effectively have 11 tie-ins counting the playoffs and access bowls.
In 2009, the SEC had 12 eligible (counting Missouri and A&M) with Alabama and Florida in the playoffs. LSU goes to an access bowl and everyone else gets placed.
In 2010, the SEC would have had 12 eligible, with Auburn off to the playoffs and Arkansas to an access bowl. One SEC team would have to fill a vacant slot elsewhere, more than likely at the expense of the Big 12.
In 2011, the SEC would have had exactly 11 teams eligible, but at least 2 would have been in the semifinals. Arkansas would get the call for the Sugar/Orange Bowl, and the Independence Bowl gets shorted.
In 2012, the SEC only had 9 eligible, and Alabama gets Florida in the national semifinals. Georgia goes to an access bowl, and Birmingham, Shreveport, and likely Charlotte are looking for teams to fill those slots.
It looks like the Birmingham Bowl and Independence Bowl may be shopping for at-large selections more often than not.
I see what you did there, but if you include A&M and Mizzou in 2010, it would be highly unlikely that Georgia, Kentucky, and Tennessee would bowl eligible (barely got by at 6-6) and you didn't include the Big 12 adding TCU/WVU which also would have been bowl eligible thus the Big 12 would not have lost a bowl bid to the SEC.
Now back on point, 75% bowl eligible is the norm for the major conferences, thus the goal is to land enough bowl tie-ins for 75% of your conference for 14 (SEC/B1G) that's 10.5, ACC w/ ND is 11.25, for 12 (PAC12) that's 9, and for the Big 12 (10) that's 7.5.
Not counting the playoff spot (since its not a guaranteed tie-in).
The SEC has 10.5: Sugar(Orange), Cap1, Outback, Gator, Liberty, Music, Texas, Belk, BBVA Compass, Independence
The Big 10 has 9: Rose, (Orange/Cap1)*, Outback, Holdiay, (Gator/Music)*, Kraft, Pinstripe, Detroit, (HrtoDallas/ArmedForces)*

Note: When the Big Ten playsd in the Orange Bowl the ACC will send non BCS #1 to the Cap1 Bowl, also the ACC/B1G will share bids in the Music/Gator Bowl each getting 3 bids to each over the next 6 years. The Big Ten will also split time between the Armed Forces Bowl (vs Army/Navy/BYU) and the Heart of Dallas Bowl (vs Big 12) each with three bids over the next 6 years. The Big Ten will also play in the new Ford/MotorCity/LittleCeasars/DetriotLions Bowl which will start in 2014 with the ACC taking voer the MAC's usual spot.
