I like that competitivecyclist.com size calculator, if only because it recognizes that different people have different ideas about how a bike should fit. The best way of figuring out what you're looking for in a new frame is to figure out what you like and don't like about your current frame - use the calculators as a reference against what you're currently riding to decide on what you want in a frame.

Also, keep in mind that most (if not all) of those calculators are for road frames - the higher BB on a track frame means that you should shave about 2cm off of the c-c seat tube measurement. ie, if the calculator puts you on a 56cm frame, you're going to want a 54cm track frame. Roughly... the standover should be around the same given a standard 11" track BB height. If you're raising or lowering your BB height from there, you may want to further adjust your seat tube length.

Also, sizing will be affected to some degree by geometry... given equal BB heights and standovers, a more relaxed seat tube angle will yeild a longer seat tube compared with a more track-specific seat tube angle.

Basically, seat tube length can be a really misleading measurement. Figure out what you want the frame to do, get the geometry to accomplish that and then let the lengths of the tubes sort themselves out. I think the angles are more important than the tube lengths.
