Could someone opine on my numbers please?

Your water is too aggressive and is at risk of etching the plaster. CSI needs to be above -0.6 and -0.3 would be better. Raising pH to 7.8 should get you there. More here, Pool School - Calcium Scaling
I just wanted to add that you're running your CYA lower than TFP specs, but I think you already know that based on your "ideal" parameters cited in your footer, right?
The water is sparkling clear.
I'll kick up the Ph, and see where I am...
I'll re check the CYA. The chlorine seems to be holding OK.
Calcium scaling is my battle... but it's hard as stone and needs to be ground off with a pumice stone.

Ok, if you're trying remove some scale then leaving your CSI at -0.8 to -0.9 will help to dissolve it. Sloooowwwlllyyy. FC is holding ok because the days are shorter, cooler and the sun is less intense.
Today's numbers after some adjusting:
FC 4.5
PH 7.6
TA 70
CYA 80 (Added yesterday)
CH 375
CSI -.57
I'M thinking I should boost TA by 20, then set the Ph at 7.6 or so. Then redo.
I'll be watching CSI as we get more rain. It seems I need to get to ~ 200 CH to get into that CSI zone. I don't want to sacrifice calcium from my plaster.
I'll keep on it after I renew my test kit.

I am a believer in the basic parameters to keep your pool trouble free. By far, elevated pH is the primary source of scale.
If you are battling scale, you almost surely run your pH too high. Keep it around 7.2 - 7.4 and NEVER let it get out of the sevens
