Calculate 90% fillrate
Hello,
I have data table with tickets for multiple issues per dates as shown below. And from which, the TAT is calculated in new column.
In another table, there is index with days from 0-1000.

Now would like to calculate in new column - new table
1) Count of tickets against each day mentioned in index
2) Avg of tickets for each day
3) Cummulative avg
4) Finally a formula which works in excel to determine the 90% fillrate
=IF(AND(I2<0.9,I3>=0.9),($F2+(0.9-I2)/(I3-I2)),0)
where "I" is Cu Avg and "F" is days.
table below for ref.
| Days | # of Tickets | Avg | Cu Avg | 90% Fill Rate |
| 0 | 4 | 33% | 33% | 0 |
| 1 | 1 | 8% | 42% | 0 |
| 2 | 3 | 25% | 67% | 0 |
| 3 | 1 | 8% | 75% | 0 |
| 4 | 1 | 8% | 83% | 0 |
| 5 | 0 | 0% | 83% | 5.8 |
| 6 | 1 | 8% | 92% | 0 |
| 7 | 0 | 0% | 92% | 0 |
| 8 | 0 | 0% | 92% | 0 |
| 9 | 1 | 8% | 100% | 0 |
Thanks & Regards,
