Pump Up Your Rating by Axel Smith

Him and Jonathan Hawkins both wrote books about going from strong club player to titled player.  Seems like those might be the idea to emulate, especially considering they didn't achieve that until they were in their late 20s/30s.

Does this book come in the e formate ? Im simply to lazy to read chess book via convention mean...

Kudos to Axel Smith. 

It's a very good book! I've owned it for about 2 and a half years now. 

What are a few of the methods outside of woodpecker talked about ?

I tried the Woodpecker method after reading the book. Amazingly I started to see things quickly and analyze rapidly, in new positions. I think it came from doing 100 simple puzzles over and over. Also the exercises he gives are quite good, but very hard for a beginner. Finally, he gives little pearls throughout the book like no break no plan. Taught me a lot.

What rating should one be before tackling this book?

2100

In learning the core principles? Any rating. The concept of unconscious bad habits->conscious bad habits-> conscious good habits-> unconscious good habits applies to any discipline of improvement. 

In actually reading the whole thing? Eh. Up to you. I'm doing a Woodpecker right now and I'm still question its efficacy but I just want to be able to say that I did one set of tactics problems Woodpecker style.
