NSW ... except yesterday was heaps lower for testing
Thats the thing about statistics - there is variability. If you look at QLD there are Sundays with higher numbers too.
Best to look at the pattern over a longer period of time and rank order highest day of week to lowest, then check the variability by which each particular day does goes outside the norm.
Sundays are always lower for testing - not sure why
In the last 8 weeks in rank order for testing (1= highest testing day, 7 = lowest testing day)
Sunday 7,6,5,7,7,6,6,7(avg 6.375)
Monday: 5,7,1,6,5,7,7,6 (avg 5.5)
Saturday 6,5,7,5,4,4,4,4 (avg 4.875)
Tuesday 1,1,4,2,6,5,5,5 (3.625)
Friday 4,4,6,1,1,3,1,3 (avg 2.875)
Thursday 3,3,2,4,2,2,2,1 (avg 2.375)
Wednesday 2,2,3,3,3,1,3,2 (2.375)
So in the last month statistically Sunday and Monday lowest testing days but Sunday not "always lower for testing"
In NSW, Monday testing has tended to be lower than Sunday (for clarity, numbers for a particular day are reported the next day)
