Re: RULES or SPECIFICATIONS?



Hi,
    I feel that if the rules or specifications are there, they should be
adhered to. Just like even though pool has different sized tables, even the
bca has specifications and tolerances as to the pool table, hole size, noses
etc etc. In addition, pool is played by humans. We have the ability to
adjust, to see whats going on.

    For a mouse, and a racing mouse to be exact, small differences in the
rules might make a big difference. For example, if the rule for the gap
between adjoining sections says no more 2mm, you might decide that a simple
roller of a certain diameter will cut the job. But if you go to competition
and find that that gap is 5mm, your roller might not cut it. But if you just
plop a big roller there, its going to be useless if the gap really is 2mm.
Cos then you would have extra weight, extra space taken up, might be more
difficult to find parts, etc, etc.

    Perhaps if there is problems with the maze you could modify ur maze
specs to be a bit more tolerant, else I feel that they should be adhered to.
