The Stoyko Exchange

The Stoyko exercise (see the description at Dan Heisman's site) does sound like a good exercise but I have almost never found the time and inspiration to get started. I think I have done it at most three times and I am probably doing it wrong since I do not get the impression that I have gained 100+ points by doing the exercise.

The obvious obstacles is finding suitable positions and to find the "true evaluations" of the lines. Using an engine will give you evaluations in centipawns but that is not too enlightening.

Any suggestions on how to find suitable positions? Does it really matter which position you use? Is there any die hard Stoyko believers out there in the "bloggsphere" who would like to sharesome positions and maybe even some evaluations?

I would love to hear about your experiences using the exercise!
