Ann: DSK FY21 Investor Presentation, page-27

I'm probably confused (and stupid) - probably because of some of the numbers bandied about above. E.g.

"Let's dig a bit deeper into the first 7 week numbers. 35% of trading days lost to closures in around 60% of the Australian population. This alone leads to a decline of 0.9 (since ~10% is online) x 0.6 x 0.35 = 19% of sales. So like for like sales in stores that are open are down around ~10%. It looks like sales between 85 - 90% of FY21 is a safe bet at this stage (there is a slight tailwind from 6 more stores opening in the first half)."

Which is different to what you are suggesting (I think?) - the 35% in the report is of all shop days over that period e.g. say there's 100 shops and 100 days in the period for a total of 10,000 shop days - 3,500 shop days would have been lost, taking into account that shops outside of lockdown areas were open 100 days, others closed for 30 days etc.?
