I agree with Steve Sherman. It is very difficult to get perfect results with pure stand development, where the negative receives no agitation at all after the initial agitation. It may seem to work fine with some subjects, say those that have a lot of texture in the scene and no large area of even tones.However, if you do a critical test, say shoot a scene with a foreground of trees, a clear open blue sky, and a white building, I think you will find that it is almost impossible to get perfectly even results.
If you are indeed getting very even development with pure stand development you are fortunate as most photographers have not been so lucky.
That said, you can increase the odds of success by using a very diluted developer. For example, if the normal dilution is 1:1:100, you might try 1:1:400, with very long development times.
