Woodpecker method

Kind of curious if anyone out there has read the woodpecker method by Axel Smith and Hans Tikkanen. I am thinking of trying it.  The author gained 3 GM norms after training with his method. Also many people ho wrote reviews on amazon and other places had good gains in rating. However, some of those reviewers have wondered how much of the rating gain is attributed to the method. Maybe the rating gain is attributed just to doing a lot of tactical puzzles and not necessarily to the method itself. I kind of thinking of doing something of a scientific experiment on myself. I have several puzzle books which include the following (1) 1000 most fameous combinations by some russian author. (2) combinations: the heart of chess by Irving Chernev (3) 1001 chess sacrifices and combinations by Fred Reinfeld (4) Queen sacrifice by Iakov neishtadt (5) Forcing chess moves by Charles Hertan My idea is to work through each of these books 5 times before trying the woopecker method. The 5 times things isnt arbitrary, On the advice with a chess coach I used to work with I worked through the 534 problems in winning chess tactics for juniors by Lou Hays 5 times.....well actually Im about halfway through the 5th lap but should finish that soon. But anyway the idea is to set a baseline of tactical skill by going through the above mentioned books 5 times each....that way when I do the woodpecker method I can be sure any rating gain I see will be due to the method and not simply due to doing a large number of tactical puzzles. My plan was to monitor my progress by doing some puzzles on chess.com after finishing each book and then after doing the woodpecker method. I think if I decide to go through with this experiment I'll make a thread about it in the forums and I'll describe my other chess activities so others can draw the appropiate conclusions. At the moment those activities include a daily chess tournament here on chess.com, an ICCF tournament , playing on a 45+45 chess league on FICS, weekly endgame lessons with a titled player. I also spend a lot of time studying opening theory in preparing for my team match games on FICS...and of course some tactics...working through the hays book. Kind of wondering if anyone has a better idea on how to do this experiment or if I study those books 5 times each I am basically doing the woodpecker method already....thus making the idea not make sense.

I am planning to ready and try Woodpecker method on chessable and now there are discount. 

If you read that Hays book five times, you have all the tactical training you need. The idea of the woodpecker method is that you repeat those same problems using less time each time you go through Hay's book. What it did for me was that it increased the speed of my analysis and helped me to develop rapid board vision. Also I see tactical patterns in my mind before they are even on the board. The disadvantage, as with all tactics training, is that you must do it daily. Or your tactics level goes down.

For anyone who is interested in following my journey, I have just started the tactical training I described at the beginning of this post. I will post updates on how it is going on another thread, https://www.chess.com/forum/view/general/tactical-training-project I dont expect to update frequently as it will take me a long time to get through a book of 1000 puzzles but I am motivated to do the training consistently and will update at some point.
