by weight percentage what is the breakdown of a trichlor puck between CYA and CL
thanks

This isn't really the right question to ask because the Free Chlorine level is measured in terms of partspermillion of chlorine gas equivalent whereas the chlorine attached to CYA is three individual chlorine atoms. When Trichlor mixes with water, it produces hypochlorous acid as follows:
Trichlor + 3H2O > CYA + 3HOCl
Trichlor + Water > Cyanuric Acid + Hypochlorous Acid (chorine)
What can be said is that 1 pound of Trichlor produces the same CYA level as 8.886 ounces weight of Cyanuric Acid. So that implies that Trichlor is 55.5% CYA by weight.
However, you can't really say that Trichlor is 44.5% chlorine. One pound of Trichlor produces the same Free Chlorine (FC) level as 14.644 ounces weight of chlorine gas so is said to have 91.5% available chlorine. One pound (16 ounces weight) of Trichlor will raise the FC by the same amount as 26.4 ounces weight of Dichlor, 22.7 ounces weight of 65% CalHypo, 14.0 cups of 12.5% chlorinating liquid, or 28.4 cups of 6% bleach.
One 3" Trichlor puck is usually 8 ounces weight or half a pound, though some pucks are 7 ounces or 6 ounces (depending on brand).
Another way of looking at this is that for every 1 ppm FC added by Trichlor you also add 0.6 ppm CYA.
