It's not as much about the numbers as it is about the overarching concepts that they bring forth.
It's probably true that some schools won't accept a student with those numbers purely to keep their averages higher.
At the same time, I think a reasonable admissions committee will realize that the important thing isn't numbers, but that the student has the motivation and desire to do well with a high load science-based curriculum, and is willing to put forth the effort to succeed.
Whatever your issues were in undergrad, it seems obvious by your post-bacc numbers that you changed your attitude and worked on the problems, and were able to get yourself in line and work to succeed.
I can't promise you anything (obviously), but if it means anything at all, I would grant an interview in a heartbeat if I were on the committee, and I would hope a lot of them would think along these lines.
To maybe alleviate some of your concerns, I had an abysmal sophomore year w/ around a 2.00 GPA and sGPA, and to top it off, that was the year I took both semesters of inorganic chemistry, biology and physics.
I did what you did a bit earlier, and pulled myself together and made kick-ass grades from there on out. I had a higher MCAT score that might have helped, but overall, our trends were similar.
Something you need to consider, though, is that this issue did come up in my interview, and were I to choose an issue they seemed to care the most about, it was what happened during that year and what changed, and what I would do to make sure it didn't happen again.
My reasoning was an autoimmune disease that ran rampant and left me doubled over for days at a time, and that seemed to be a valid excuse to them (excuse, reason, whatever...excuse seems to have a bad connotation)
While your trend of poor performance was longer, your later numbers seem very much up to par.
Would you mind if I ask how long your post-bacc tenure was? The longer the better...one semester of good grades after those undergrad numbers doesn't look nearly as good as a year or two.
Either way, I think you'll at least be granted an interview. Good luck! And remember to consider your answer to why that happened and what you'll do to prevent it's recurrence. I guarantee that will come up, if not be the only thing discussed.
