Basically this means that we should NOT see max boost on a cool day at sea level etc.
This is what would be interesting to see some datalogging of as well. This would be of most interest on a stock engine and no tune.

I have datalogged and we do see max boost. When the conditions are worse, we see more than max boost (up to 20)...and yes, with no tune.
