Help understanding Sophie’s CFA Study Planner

Hello everyone. I’ve downloaded the CFA Study Planner from here: https://300hours.com/cfa-study-planner/

And I’m interested to know the difference between CFA Curriculum Pages and Total pages to cover. Looking at the CFAI book 1 (Ethics and Quant), ethics is 270 pages and quant is 500 pages exactly. By default the downloadable spreadsheet has 85 pages for total pages to cover for ethics but what does it mean?

Also what does the spreadsheet mean by number of study sessions?

Is my understanding correct that by Sophie’s schedule it’s reasonable to cover, note and remember all of ethics in three days if I were to study twelve hours or is that for me to work out?

I’ve attached screenshots of the spreadsheet I’m dealing with.

All help is appreciated.
