Hi Tony
It is the variation in noise level that gives that effect. On my RP could shift over a huge range; engine noise level varied enormously but the top speed remained the same. Manual advance gives you something to while away the time when climbing...or accelerating. With wear and springs of uncertain providence never really sure if auto advance is optimal (ie just as much as necessary for performance.)
For cars converted it is worth retaining the manual as an override. Enables the optimum setting without use of the kitchen clock. A light spring on th linkage eliminates backlash.
Influences hill climbing more obviously.
