<pre>Currently, the exclusion zones of a touchpad is set at 8% of the width on
either sides and 5% of the height at the top edge, if my understanding is
correct.
For extra large touchpads such as ones on newer MacBooks, however, the
exclusion zones are too large. E.g. the touchpad on 13-inch MacBook Pro
measures at 135x84mm. 8% on both sides means more than 1cm on both sides of the
touchpad cannot be used.
Given that touch-size-based palm rejection is working quite well in most
situations, exclusion zones as narrow as 3mm on both sides and the top are
sufficient in rejeting accidental touches on the edges in my own tests.
