Tc and fc confusion

So with tfp there is an importance to the fc/cya relationship. I’m confused though. We bought the t-100 kit on the tfp site and it says to test the total chlorine daily with the blue box kits k-1000. It also says tc should be at least 2 ppm. That seems low since fc starts at 3 ppm on the cya/fc chart. What are we not understanding? And shouldnt we be testing the fc daily?
