The chart doesn't include the intercooler used, and the intercooler cfm airflow or outlet air temperature either... thats very important when figuring "Compression Ratio vs BOOST - Knock Control"

Compressing air quickly heats it up in a big way and that increases the chance of detonation.

So if you compress the air to around 14psi in the turbo and then cool it off good in the intercooler before compressing it very quickly some more in the cylinders, that helps alot for knock control or detonation.
