it's know odds and percentages "mythical" seems to be more the word but "science" I guess could be used for tells in a live limit game (or online if you have one).
Mythical??? Not sure I follow.

The reason Limit IS a science - In most situations there is a cut and dried correct play. Small variations may be made based on the playing style of your opps, but overall you can play cookie-cutter poker in limit, and be assured of winning at the low limits.
