Starting with liquid chlorine

After many years of pool ownership and battling rising CYA due to the trichlor pucks, I am starting off this season using liquid chlorine based on all I have read on TFP. I have my TF Pro test kit so I can manage the numbers myself. A few questions:

19,000 gallon pool is vinyl so I know I need to take some care - is it worthwhile to dilute my 12.5% liquid chlorine in a bucket before slowly pouring it in? Any other tips for adding to a vinyl pool?
Should I expect to have to add some liquid chlorine daily?
Besides routine use, the Liquid Chlorine label says to also put in 50-100 ounces/10k gallons weekly to super-chlorinate. Really? If no algae or other problem do I need weekly shocking? Same question for algaecide - can I stop that as long as no problems and I maintain free chlorine?
I read that liquid chlorine raises pH, but I do not see that on "Effects of Adding" on the Pool Math app. Does that mean the pH impact is negligible?

Many thanks in advance!

No. Add the liquid chlorine in a pencil size stream at a pool return with the pump running. Brush the area if you wish.

Yes

'Shock' and algaecide are not needed.

The addition of liquid chlorine to pool water (and the resultant reaction with UV and/or organics) is pH neutral.
