Should I Use Scents on My Lures?

Fish smell in parts per million and who's to say how much scent we should put on.  If we load the lure with a gel, and the water is cold, not much of the scent will come off since it is thick and coagulated on the bait.  When the water is warmer and the gel scent is more viscous, it will come off easier presumably giving off more scent.  Should we put less on in the summer and more on in the winter.  Fishing has always been about the little things and taking into consideration these and other factors may make a huge difference.
