Time Step

Is there any reason why the drop down on time step shows values that are the reciprocal of 2,4,8, 16..128

(Though one can key in a value other than those in the drop down if they choose to)

Powers of 1/2 give you a time axis that will hit the integers. If you use .001 as a time step from 0 to 20 you might get 9.999997 as a time point instead of 10. For the most part this is purely asthetic as it does not really change any results.
