Rather than an informal online poll of a smallish audience, I would think a better justification for reducing your sampling requirement(s) would be historical data based proof that you are producing in tolerance product, and that your processes are stable, reliable, repeatable, and well managed. Any proposal to reduce sampling should also define the trigger(s) that would require more sampling should quality begin to slip over time.

So a little history. The company I work for has changed their sample plan probably 3 times since I have worked here in the past 2 years. Always by people outside of quality. The last time it was changed I was on my honeymoon and they changed it without me knowing while I was gone because I am sure they knew I would have raised a red flag if I was there. (that person is gone)
I am finally having an opportunity to give some feedback on the situation with a recent change of leadership. Even though we are technically using Z1.4 AQL 1.0 C=0 and MIS-50822 we have a grab bag of numbers for a few of our inspection levels. I am merely trying to gather information so I can make a more informed answer. I am not trying to reduce our sample plan to cheat the inspection, I am trying to have a sample plan that is statistically sound and know that we are not over inspecting.
This can of worms was opened because a customer sent us their preferred sample plan and it was about half the size of our sample plan so we are clearly over measuring these parts.
Although it is not my fault it is my responsibility.
