RE: mouse performance

["Daniel Chia" <danstryder01@yahoo.com.sg>]

Hi,
	Actually I think it was mentioned before that cornering speed is
also quite an important factor when it comes to deciding the speed of a
mouse, since a mouse does corner frequently and having a higher average
speed is greatly facilitated by turn speed.
