Don't forget, you can also type in decimals for less extreme adjustments. ie; 96.7

  There is definitely some trial and error.  After printing a step wedge test
  file, scan it.  Use levels to put the 0% and 100% where they should be.
  Then read the values of the other patches.  If, for example, the 95% patch
  reads 97%, try putting a 94 in the 95% box of the Transfer Function.  (It
  tends to overshoot.)  Then print with it and see what happened.

  Don't expect to get the exact values all the way.  If you make too many or
  too radical adjustments in the Transfer Function the ramp get ripply.  So,
  go easy and slow, saving the files as you go, and marking the test prints so
  you can conclude after you've gone too far which made the best print.
