I would say that the measurement of progress would be an individual thing. I have been pleased with my results particularly with direct learning. But then again I expect to succeed.
Things like my spelling improving, being able to rapid read and comprehend quicker, having a feeling like I am already familiar with the material, spontaneous activations, etc. For me this process has been quite a success. Of course I am striving to improve in many areas. For example it would be great to be able to recall the material as well as Pete does but that will come with time.
