Higher line voltage also a very valid factor....

Yep , the voltage figures on the schematics were likely taken with a voltmeter with around 10K ohms per volt loading , wheras modern meters are much higher (Maybe 1 to 5 Meg per volt ?) . Since the new meter puts less load on the circuit the voltage reading is higher .
Solution = get a nice old VOM like my favorite , the old reliable Simpson 260
PS , Most voltage charts will have a caption somewhere saying "Voltages measured with 10K per volt meter" or something similar .....
