I think that if you disconnect the vacuum hose from the distributor you can measure the max advance by using an adjustable strobe on the P mark with the engine at 5000 rpm. If for example it is 30 degrees when your static is 7 degrees then you would move the static to 11 to get 34 degrees max advance.
Also, the manual says disconnect the vacuum hose to check the static timing.
