To be honest, I don't even know what average EC's would be.

Low MCAT and Low GPA cannot be replaced with above average EC's in my opinion
Agreed although it depends on what is defined as "low". I know sometimes we refute a claim like this but an applicant with 3.1/3.1/500 has more than a decent chance at acceptance somewhere if they apply broadly and early
The claim is refuted because all statistics say otherwise. You have no evidence to back this idea of "more than a decent chance at acceptance" up.
To answer your question, @DrH2O, I would say that ECs can replace GPA to a certain extent. Not so much the MCAT. Before I matriculated at my undergrad institution I met with an admissions counselor for our medical school. Was thinking about playing a varsity sport and asked him what this would mean to their admissions committee, if they would give me the benefit of the doubt on my gpa, etc. Average cgpa for med student at my school is 3.8. Said if I played a sport all 4 years of undergrad 3.4 would be completely fine and that they would understand that. Actually know someone at the school now who played a division 1 sport 4 years and did not even have that GPA, but had a solid MCAT and is doing absolutely fine.
To me, it depends greatly on the EC. Anyone can volunteer for 100 hours. You need to separate yourself. And then on top of that be able to show how your commitment to your EC may have influenced your GPA, but it made you a well rounded and overall better candidate because of it.
MCAT, in my opinion, does not have this leeway, as it is much more indicative of knowledge than GPA.
And I am talking about specifically DO schools. No DO school had an average GPA of 3.8 like your undergrad's medical school. I stand by what I said, an applicant with a 3.1/3.1/500 stands a good chance of at least 1 acceptance.
Actually there is evidence to prove this. For starters go check the underdawgs thread and see how many have acceptances with numbers LOWER than that. And that is only a super small pool of applicants. I would bet good money that about 40 % of DO applicants have around those numbers give or take a few points. There is a reason the "10th percentile" is not published for DO schools. More than a few matriculants have numbers at or below 3.1/3.1/500
