[r-t] Poll on consecutive blows in the same position

[Mark Davies]

Don keeps bringing up the subject of "rule-based methods", AKA 
dixonoids. Whilst it is worth thinking about these at some point, here I 
think we need to remain focussed on "lead-based methods", or, as most of 
us call them, "methods".

I don't think there is any horror here. The "non-method blocks" recently 
introduced by the MC fall into the category of "lead-based methods" and 
so should be able to be described as methods. This is why the "block" 
concept is unpalatable for this application. Dixonoids, on the other 
hand, are so different in construction that it can only make sense to 
consider them separately.
