Here's actual flight data from the Hurricane using 6 and 12lb boost:
Note how closely the performance increases match the previous data for the Spitfire I at 6 and 12lb boost.
I haven't read of the Spitfire I/II using 16lb in combat, but they must have run the Merlin III at 16lb boost to certify it for the Sea Hurricane, and those tests are just as easy to do in a Spitfire with a Merlin III.
