More on the "Chess-Steps Method"

 At this web page 

 we read that specific books are recommended for players having a target rating. For instance:

• Step 4 Workbook & Manual suit players having an USCF rating up to 1750
• Step 6 Workbook & Manual are recommended for players USCF rated up to 2100

Somewhere I read that Fide Ratings are about 100 elo points lower than USCF ratings. I have wondered if these indications were really correct or if they were a vague guess only. So I made a research on the Internet in order to find  if other chess players, besides me, had published any report of their own success/ratio in solving the Chess-Steps Workbooks.

Unfortunately I found only one.
This is the link:

There we can read what follows:

5 december 2009 - Step 6 and Stoyko exercises

At the moment I use two training methods. The first is step 6 of the steps method. I already did this book once (over a period of more than a year) and had an overall succes rate of about 85%.
At first I thought it would be best to concentrate on the exercises I failed to solve. But when I started to pick up the book I noticed that I didn't remember most of the (1300) positions. For this reason I decided to go through the book again. Not surprisingly my succes rate is now about 95%, and I also solve them a lot faster than I did the first time. I consider this work to be largely a kind of maintenance of acquired patterns. (...)

 In another post written on 25 February 2009:

the author states that :
"(...) I think that for a player of my strength (2050+), (...)
so, that player had a Candidate Master rating at the time he was solving the Chess Steps 6th Workbook.

As my own final success rate of Step 4 is about 95% (my current FIDE rating is 1780), in absence of additional data, for the very limited info/reports in my hands, I suppose that the rating indications provided at http://www.chess-steps.com/index.php may be accurate.
If any reader has gone through the chess-steps workbook and he/she would like to share his/her success ratio, please send an email at ricettario@fastwebnet.it so I will be able to update this post. Thanks.
