Forest-based Classification and Regression tool - Validation Question

I'm assuming the "Training Data Excluded for Validation (%)" option takes a random subset from your data points to hold back. If I withhold 30% of my data, will it always be the same 30% of points? Or will it change each time I run the tool?


If it does change each time, is there any way to change it so that it will use the same validation points? I have a sneaking feeling I may have to edit the python script, but my programming knowledge is pretty limited!


Any advice is welcome!
