Look at MDM’s rapid rating before you trust his claims. He knows how to tell a story to sell a book. He had financial resources and no responsibilities, devoted two years to chess, briefly cracked 2000, and then quit. His book is a con.
There are quite a few people who question de la Maza's claims (some assuming he found a way to cheat and just did not get caught). While possible, it doesn't change the moral of the story much in my opinion. While there is a large gap in his rapid rating, he only has 4 games in 1 event (over 2 years before he won at the World Open), so there simply are not enough games the make a decent comparison.
Hans Tikkannen did something similar to make his push for the GM title in his late 20s (the Woodpecker Method).
