Dear Friends,
On August 3, there were (2000 + 62 + 175 + 25 = 2262 ) ppl in the pool with CRS >= 433 .
So in 6 days (2991 - 2262) = 729 ppl with CRS >= 433 have joined the pool.
729/6 = 122 per day.
It is very good news.
I have a hope once again.
If you were to assume that there were 1600 people greater than or equal to 433 on August 3, your method would yield 1129/6 = 188 per day. So a lot is relying on your assumption of 2000.
