Didn't make much progress yesterday:

FC=5.5
CC=0
PH=7.5
TA=120ppm (started at 130ppm--drifted up 10 from day before)
CYA=95ppm (retested this to verify)
CH=680ppm (tested this twice yesterday to verify)
Water temp=86

I used a total of 6 cups of muriatic yesterday evening, trying to break that magic 100---I'll do some measurements this afternoon to re-check. Waterfall had my PH from 7.0 to 7.2 in about 2 hrs, so I covered the pool and called it a night at around 7:45pm.
