Calibrating it doesn't give you better battery life, just better readings, which is important for you but not for the battery.

That being said, I am at 49 cycles and my battery health is 100% according to iStat Pro. My battery charge is 38% and charging (I've been at school all day and only started charging back up right now).

If I was you I'd be upset about my battery life, too, but I wouldn't take it to Apple because they would not be willing to help you. Forget about the 4% battery life you lost and focus on taking care of the 96% you have. Follow my suggestions and you will have a good battery!
I don't know where you are getting your info from but this is not accurate at all!
If you want maximum battery life, you are supposed to charge your battery, unplug it once fully charged, run on battery power until the batter warning comes up, let it turn itself off, if you can, leave it alone for a couple of minutes after the computer shuts itself off, then plug it back in and you start all over again! Having 49 cycles at 100% health is nothing amazing...it's a new battery that is expected to last 1000 charges before you start noticing abnormal battery life! There absolutely IS a direct correlation between the battery life and battery readings!

unless others and I are completely wrong!
