Rat bastards. ;)
Guys thanks for the input, I managed to resolve this issue last night with your advice. the Problem was 80% my fault and 20% front focussing, it seems. It seems to be better now, but will tweak on from here.
I appreciate the assistance.

Awesome. Thanks marc and co for the chart links.
After reading your comments, I am starting to wonder if this is indeed back focus or user error, mmm.
I did notice though that I don't have any problems outdoors, tested today after I made this post.
I will test indoors tonight.
Thanks!
My engineering concern is rather, why doesn't sigma lenses report their id to the camera, what so hard about that :P

Hi folks,
Im a bit confused, not sure I understand what back focus really is, and if I do, I don't think I know how to handle and deal with it.
I have a K20D so I have the ability to set back focus on the camera, correct?
Well, I find that alot of my photos (using my Sigma 18-50 DC EX 2.8) are not focussed where I thought they should be (on apertures between 2.8 and 6.7). So maybe it's just a DOF issue, but maybe not.
What is the best way to test/check for back focus, and if I find any, how does it work to correct it, I don't understand the k20D manual, its vague.
Maybe I am just an idiot and all of this isn't even happening, feel free to point fingers :o
