I've been working about year to get my CYA and CH in check through partial water exchanges. My current CYA is 40 ppm rounded up from between 30 ppm and 40 ppm. Knowing the effort it took to complete this, I'd really prefer to keep the CYA on the low side, but I'm noticing how much liquid chlorine I'm going through on full sun days. My logs are up to date and I'm having to add 90 ounces of 10% liquid chlorine, which according to PoolMath effects of adding this equates to about 2.5 ppm of chlorine loss per day. Is this expected/reasonable? My pool is crystal clear, passes the OCLT, and has 0 ppm of CC so I'm confident it's not increased demand from algae.
Expected summer FC loss/day?

Yes. Here is the deal. SLAMing with CYA of 60 is easy. Above that, not so much. I'd run your CYA up to 60 in TX. Will reduce FC usage, but still allow you to slam easily.
Always follow this and keep FC at top end of the range (#TeamRunHot). Link-->FC/CYA Levels
Seasonal UV loss is like a bell curve with little at the ends and more in the middle. There are occasional whoopsie weeks in there but for the most part, it follows the general schedule.
Those in hot climates may see 5 ppm lost daily in the peak season while it might only be 3 in Toronto.
