Tabulating/computation of daily participation rate for survey

I have an excel on ‘Staff List’ which shows the people who have participated in the survey everyday, separated by different daily tabs.

I have another excel ‘Tabulation’ which will calculate the % of people who have participated in the survey by extracting the count from ‘Staff List’, but the columns would add on by day as it would be computed daily.

There is a ‘Template’ tab in the Tabulation excel file where the data would be fixed and the output I want would look like the tab ‘Output’ in the Tabulation excel file.

I did a very draft workflow but I can’t figure it out because there are so many requirements.
