Are we talking at cross purposes??
Nick has quoted a magneto engine handbook. I think that a mag gives a stronger spark when it is advanced up, to do with internal timing, i.e. points opening vs. maximum flux. So the distributor stuff doesn't apply in this case......
And maybe Austin technical authors didn't change this when coil ignition was introduced......
