Compression - How much is too much?

Search around on google, there will be plenty explanations. One example:

I don't want to deny any positive effects of the higher compression. I just said, higher compression will consume more air, and the ECU will compensate for it. Measure the air volume either case, measure the AFR accordingly, you will see the ecu trying to keep up.
But have a look from the other side: use slightly bigger cams, no shaving, no thin gasket, nothing. How the hell the ecu can compensate (up to a limit, of course) for the different than stock lift and duration, if it can't measure the air? Hence the question, what do you think what is the correlation of the static and dynamic compression?
