[Healeys] spark plugs

[Mirek Sharp]

Comm'on Peter - you jest I know - that does not mean anything unless we know 
how many duff NGK plugs were fitted to Datsun pedal cars, or Bosch to 
Mercedes pedal cars!  We would need to run some stats to see if what the 
standard deviation is and if there is a statistical difference. Champion may 
have produced a smaller proportion of duff plugs?

My theory is that the vast majority of plugs are as good as one another and 
that our perceived differences among them are based on small sample sizes or 
flukes.  Based on chance alone, someone has to get more duff plugs than the 
rest of us, it seems Ed drew the short straw!  Some previous responder 
indicted that we tend swear off many products after one bad experience, and 
that is the basis for my initial "myth" reference - that is how myths grow. 
that comment was right on!

Sorry for stretching this out - I really don't care and I doubt any of this 
will change our plug habits!
