Does anyone running the NGK, Champion or AL plugs have any documentation for deciphering the characteristics of the plugs from their number?????

I have an older AC book that deciphers the numbers and have looked at several AL books. The AL books seem to be rather ambiguous and lacking detail.

I've never been able to find ANY information on ANY plug that was reasonably complete EXCEPT the AC.

Again, if the OLD Champion,AL or AC numbers can be decipherd according to plug CHARACTERISTICS then the NEW books can be used to determine a modern number for a modern plug with the same or very close characteristics.
