 MAXOVERLAPANGLE [double]
     Angle threshold to use in filtering out ANGLE FOLLOW labels in which characters overlap (floating point value in degrees). This filtering will be enabled by default starting with MapServer 6.0. The default MAXOVERLAPANGLE value will be 22.5 degrees, which also matches the default in GeoServer. Users will be free to tune the value up or down depending on the type of data they are dealing with and their tolerance to bad overlap in labels.
-    Setting MAXOVERLAPANGLE = 0 will completely disable filtering of labels based on this criteria, restoring the pre-6.0 behavior.
+    As per RFC 60, if MAXOVERLAPANGLE is set to 0, then we fall back on pre-6.0 behavior which was to use maxoverlapangle = 0.4*MS_PI (40% of 180 degrees = 72degree).
 
     The associated RFC document for this feature is :ref:`RFC60`.
