The default sizes (12pt, 11pt etc.) have fixed values for x and xx, you 
can see them in font-pre.mkiv:

\definebodyfontenvironment
   [\!!twelvepoint]
   [        \s!text=\!!twelvepoint,
          \s!script=\!!ninepoint,
    \s!scriptscript=\!!sevenpoint,
               \s!x=\!!tenpoint,
              \s!xx=\!!eightpoint,
             \v!big=\!!fourteenpointfour,
           \v!small=\!!tenpoint]
