As an example, in a late 50 and 51 advance table the numbers were:
200 rpm 0 degrees
500 rpm 1 degree
1000 rpm 6.25 degrees
1500 rpm 10 degrees
2000 rpm 11.25 degrees
Those are the max values in distributor degrees, so with 2 initial it would be:
200 rpm 2
500 rpm 4
1000 rpm 14.5
1500 rpm 22
2000 rpm 24.5
Which seems a lot more reasonable to me.

Those charts are 32-41 helmets , the load a matic is a totaly different discussion. The load a matic have a ton of advance available , however with venturi its a total different spec ( and a different engine)/I will dig up some specs on those this week as i am presently working on a couple.....
