Findings of the last week is normal, nothing abnormal found.
Because, the total distributed merits over the last week is 4050, which is in the range of 50% previous period weekly merits, with the median found at 4423, and the interquartile range from 3854 to 5487.
I meant for weeks with total merits range from 3.8k to 5.4k, there is no reason to pay attention and dicuss about them, because they obviously have normal distribution of weekly merit.
