Unusual but not unexpected.
This Apple article has a subtle bit of wording that probably explains what you see:
If the battery is removed from a MacBook or MacBook Pro, the computer will automatically reduce the processor speed. This prevents the computer from shutting down if it demands more power than the A/C adaptor alone can provide.
This seems to say Apple anticipated some very demanding apps would need extra power, requiring the battery to supplement the A/C source.
The fact that your fans spin up supports your observation about the app being a kludge-hog.

Skype video calling is a monstrous energy hog, and when you do it, your MBP is demanding more power than its AC adapter can provide. Under those conditions, the battery is drawn upon to make up the power deficit. This is by design, and is the way the machine is supposed to operate.
To limit the impact of Skype video calling, you can either a) not do it, which is what I recommend, or b) make sure nothing else is drawing power at the same time: no bus-powered peripheral devices connected (hard drives, iPhones, iPods, iPads, mice, trackpads, joysticks, etc), no other apps running, and no power-hungry background processes eating up processor cycles.

Helpful but mine has a non removable battery thusly what happens when my battery hits zero? let alone the AC adapter SHOULD be charging the computer or at least preventing batt drain as the app is causing my mac to be at -.6 amps per hour. charger max is 4.6 amps max so therefore the app must be drawing approx 4.6 amps... why the **** it is drawing so much I have no idea.
heck its the most resource intensive thing out of all my processes right now...
all i can say is what the heck is up with this crap?

i disconnected everything from this mac. 2 hard drives and still very similar amp draw is showing in minibatterylogger. why is it that this just started up in the last 2 weeks all of the sudden when i have not changed settings or my behavior, only installed an EFI update and some other apple updates...

also mark my words here this behaved fine 2 weeks ago even with the drives connected. so this is very confusing and angering.

You may want to try resetting the SMC:
Doing so can sometimes sort out power-related anomalies.

odd enough i have reset the SMC several times but will try again this time with nothing but the adapter plugged in.

still didnt work as expected but i found a temp workaround. i use CamTwist to run the camera and Skype running through camtwist. forces skype to not use its codec and forces use of the QTKit Codecs.
Its their codecs causing my computer to SUCK power. so I will file a bug report in their bug tracker.
