I'm not quite sure why the email below hasn't reached the

I think Robert is right because after you've rewritten a touch in this manner, 
there's no longer a guarantee that all of the leads join up into a single round 
block.  It's possible that you might end up with a few spare bob courses (or 
other round blocks) that detach themselves from the main body of the 

The situation is the same in doubles.  Every extent of Plain Bob Doubles (of 
which there's only one, pppb x3) can be converted to an extent of St Simon's 
Doubles.  But not every extent of St Simon's can be converted to an extent of 
Bob Doubles.  In particular, bbbp x3 is a valid extent of St Simon's, but if 
you try to convert that to Plain Bob, you end up with a 60 (bp x3) and three 
20s (each bb).
