Feel like a bit of a pest...but after more reading, I'm wondering why (in my case) no one is suggesting that I partially drain the pool? I'm sure there is a reason, but I don't know why.

I'm wondering if it'd help to partially drain - ie, wouldn't this both lower the cya, which then would lower my chlorine burn...so then I could deal w/ the short term imbalance (using less chlorine) while also ideally prepping my pool for longer term BBB method? In other words, don't I have to get rid of a high cya (now at about 180) at some point anyway, so why not now? What am I missing?

My water is totally clear, no algae...tho I understand the high cya may indicate a near-future bloom.
