I don't know if I have seen anyone here have their CYA that high! , Then again I've only found this wonderful place last April...

That's an indicator that you are killing the organics (algae) in your pool so the FC is not consumed so fast. You don't say what FC you started with prior to your abasence so it is difficult to assess your situation accurately.I was surprised to see so much FC still in my pool, 24 hours after adding it. Normally it would be all gone by now.
No need. You are correct, unless you drain or add water CYA will stay virtually constant in your pool for at least a month or so.I will test for CYA again tonight, before I go to bed.
