Is this what you were after:

Code:
awk '
   { for(i=1;i<=NF;i++) {
      max=$i>max?$i:max;
      if(!(++cnt%3)) {
          print max;
          max=-999;
   }}}
   END { if(cnt%3) print max }' file

@Corona688 - One word per phone call - Nice analogy, I'll file that one away for later use

DESCRIPTION

       Each of these functions finds the first element with the maximum magnitude in a complex vector, then puts the real and imaginary  parts	of
       it into max[0] and max[1], respectively.

PARAMETERS

       Each of the functions takes the following arguments:

       max	       Pointer to the first element with the maximum magnitude.

       x	       Pointer to the first element of the source vector.

       n	       Number of elements in the source vector.

RETURN VALUES

       Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
