 <h2>KNOWN ISSUES</h2>
 
 <ul>
-<li> <em>n</em> map sum can be ever-so-slightly more than `<tt>wc -l</tt>`
-  with e.g. <tt>percent=10</tt> or less.
-  <br>Cause unknown.
-
 <li> "<tt>nan</tt>" can leak into <em>coeff_var</em> maps.
   <br>Cause unknown. Possible work-around: "<tt>r.null setnull=nan</tt>"
 <!-- Another method:  r.mapcalc 'No_nan = if(map == map, map, null() )' -->
