I believe as long as you don’t “use” last months figures until at least reply_within_x_days
after the last day of the month these are good numbers.
Actually I’m seeing 1
days (78.6%), 4
days (78.6%) and 15
days (79.5%) for one sample set of data - so you could pick a smaller number of days and measure that, Yes 1
day and 4
days are the same.
