Agree 100%. I was doing the math comparison purely for my own academic curiosity.
For background, I started off with trichlor in my new pool at the beginning because I had to wait 30 days before turning on the SWCG, trichlor was convenient and added CYA, and liquid chlorine was incredibly hard to find at the time. I tried my SWCG after the 30 days, but it has been having intermittent issues, so I continued with the trichlor until my CYA hit 60. That was around a week ago, at which point I switched to liquid chlorine while the PB sorts out the issue with my SWCG.
