Thanks for this draft – I think it is very close.
Regarding the question on “margin”, while I may be asking for too much, it would really be great if we could ask for the standard deviation on the sensitivity. Moreover, we
should clarify that the “sensitivity” we ask for is the mean (or typical) value.
If we could get mean and standard deviation, then we can properly account for spec difficulty vs. yield trade-off.
As it is now, I think there is a potential confusion in that some people report their typical number, while others will report their maximum (worst) sensitivity. And different
people have different levels of pain tolerance. For instance, some may be comfortable with a 1dB margin, while others like 2~3 dB of margin.
Thanks, Frank E.
