This topic has been laboured on many occasions. The Manual are set at full advance. If the car is not to be driven by strangers extra advance can be allowed and used primarily for experiment. For ordinary cars driven sedately many consider about 1 1/2 advance adequate.
The Manual advice wrongly repeated for the Auto in 1st Ruby handbook and repeated in many other books has caused endless confusion and needless engine stresses over the decades.
Actual characteristics of present day auto distributors is anyones guess.
My 13.11.17 post under 65 Timing covers the topic. Other posts refer more to advances for the rpm and ultimate power enthusiaits with new cranks.
Advance is very stressful of crank.
One inch on flywheel is 11 deg.
Noise is not necessarily an indicator of power.
