Maybe a compromise in the debate is to look at the time he recommends you spend on the micro-level drills vs. the 7 circles. (Looking at the Skittles papers and hoping the recommendation in the book didn't change.)
"At the end of the Seven Circles training you will have spent a total of 155 days (28 days doing micro-level drills plus 127 days doing Seven Circles) working on your tactical training ability. If you work through the program exactly as I’ve described it, your tactical ability will soar."
28/155 = 18%
Of course, I don't know how effective the micro-level drills actually are vs. the 7 circles.
Your summation was inaccurate and biased. Just accept the fact instead of attempting to justify it and try to be more objective in future. Also your statement of 2% and 98% is demonstrably false, there are 6 chapters,
1. chess vision skills, 2 the seven circles, 3 how to think, 4 practical tactics, 5 success with rapid chess, 6 what to do next.
pages 25 to 41 are devoted to chess vision, pages 41 to 60 to the seven circles. That is 16 pages and 19 pages respectively.
Yep, of which this is the relative value of what the contribution of each is to his training results:
- Doing 7 circles: 95%
- Everything else: <5%
So I stand by my accurate summary. If you disagree, I guarantee that take any beginner, make one do the 7 circles only for a few months, and have the other do 'everything else' while completely omitting the 7 circles, and it'll be pretty clear who's improving and who isn't.
His system is ALL about tactics. You're fooling yourself if you think it's not.
No one has claimed that his system is not all about tactics. Your claim was that chess vision takes up 2% of the work and the seven circles takes up 98% of everything else and was demonstrated to be false when I produced the pages devoted to each subject. You have now attempted to state that it was based on some kind of relative value, which you seem once again to have fabricated based on nothing more than your own opinion.
A piece of unsolicited advice, its difficult to argue against empirical evidence with nothing more than mere opinion :D
