Just a correction....I wanted to add on let's take it that we have a 50% respond rate....and 40% holes and so we can say we have 10%(refused, ready( but did not process) and those that did not process at all)....then the cut off can be 1700....Honestly this doesn't look good for anyone over 1450....so did the calculation as such....so according to this forum the highest CN=24×× so I am taking 2500 highest cn.....so lets do the calculation....
Selectee no#=2469
Highest CN= 2500
2469÷1.60=1544
OR
2469÷1.65=1497
So
1544÷2500=62% real cases
OR
1487÷2500=60% real cases
So now if the year goes well with no covid and all(which will not be the case) den the cut off would be
Scenario 1(2469÷1.6)
Cut off=1370
Scenario 2(2469÷165)
Cut off=1416
So let me kmow if I am wrong...
