RE: Rules

["Edmund Stephen-Smith" <edmund@stephen-smith.org>]

Personally, I think the NSEW explanation is OK.  But we could replace:
	"The starting square orientation shall be such that when the open wall is
to the 'north', outside micromouse maze walls are on the 'west', and
'south'."

with something like:
	"When a mouse is placed in the starting square facing the open side of that
square, one outer edge of the maze will be on its left side and one outer
edge behind it."

I hadn't thought about the confusion between 'relative north' and 'absolute
magnetic north'!  I didn't think that this would be an issue, but now you
mention it, Duncan......

My original point is that the phrase, "...when the open wall is to the
north...", is ambiguous.  What about when the open wall is not to the north?
What about if the open wall is to the east?  The outer maze walls can still
be to the west and south in this case.  If the rule is intended to define
the northerly maze orientation as that direction in which the open wall
shall face, then this should be explicitly stated.

I am probably simply mis-reading a simple rule - but, surely, if a rule can
be mis-interpreted by thickies like myself then the rule needs re-stating
more clearly?
