5 mil is true for single smaller targets than need accurate aiming with weaponds that demand it eg MK-82. With CBUs on concentrated targets 3/9 works well also.
What we are missing here for CCIP CR mode is the fact that it's the only method you can use for targets of oportunity, where you fly relatively low (you can't spot targets of oportunity high) and you don't have the luxury to Laser designate/SPI/Slave all etc. according to CCRP demands.
So in situation like this above, CCIP in CR mode is the best you can do in my opinion. You directly aim in CCIP, concent to release (CR), quickly level AC (equals to tossing) avoiding low altitute crash dive, and target boom ! :smilewink:
