I'm afraid I also don't really "get" it.
Grouping kanji by visual similarity is of course highly useful to prevent students from mixing them up: 限 and 郎, 牛 and 午, 昆 and 皆, the usual suspects. However, it's not a new concept. Grouping 牛 and 昆 because they're both animals on the other hand might be new, but I'm not sure what value that has.
Ordering kanji by frequency of use would mean that you first learn 時, 待 and 持 and only then 寺. That you first get to see 挑, 眺 and 跳 and only then 兆. Presenting them in the reverse order would make it easier to learn them, no?
I think I'm failing to explain how the book is arranged. I'll show it step by step:
- First you learn 145 radicals at once (although they are already grouped by topics)
- Then the book gets divided in levels of difficulty based on school grades, from level 1 to 6 and then secondary school. Each level is a different chapter.
- We go with the chapter 1 (level 1). The chapter first gets divided into topics (human world, natural world and man-made world).
- Lets start with the human world.
- There we got the first phono-semantic compund: 交 (garde 1), then we have the character 校 (also grade 1), and then the character 効 (grade 5)
- The characters 絞 and 郊 also share the component 交 but they are of the secondary school level, so I left them out of the chapter 1.
Taking the examples you mention: 牛 and 昆.
牛 is a radical so it is place in the chapter 0 (radical chapter), "nature world - animals" section along with other such radicals like 虫, 魚, 隹, etc.
The character 昆 is not an animal, although is primordial use in Japanese language is within the word "insect" (昆虫), its actual meaning is "descendants". An "animal" component that is not a radical is, for example the character 皮 (a hand ripping off the pelt of snake):
This character, being within the 3rd school grade, appears in the chapter three, appears within the "natural world" section of that character along another characters that share de component (below the secondary school level) such as 波 and 破.
The book is divided in chapters and each chapter is divided in topic section.
The sample page explains 交 using a "crossed legs" mnemonic and completely disregards the fact that it's just 亠 + 父. In fact, the dissertation about radicals calls 亠 "completely irrelevant" even though it's used in 卒, 方, 文, 亡, 夜, 衣 etc etc.
交 (exchanging) is not 亠 + 父 but a evolution of the glyph
, a man with crossed legs. The mnemonic derives from the actual etymology because I think that making up "random" mnemonics fails on taking the advantage the characters give you (albeit hidden by the glyphs' evolution over the years) in order to learn the system faster and more cohesively.
父 (father), as the standalone character, is the derived form of a completely different glyph:
(a hand holding a stone or tool).
衣 (clothes) is just a spread garment:
卒 (graduating) is a tied (ceremonial) garment:
方 (direction) is the hilt of a sword or knife:
文 (letters) is a tattooed person:
亡 (deceasing) is a person buried in a hole:
夜 (night) is a person in front of the moon:
As you see none of those characters has anything to do with a supposed (made-up) 亠 component. I think these kind of made-up components just give confusion.
IIn addition, no sample word is given for the common こう reading (e.g. 交換, 交通).
The reason I don't give those words there is because I don't want to show words that have a kanji not studied yet. Those words will appear respectively with the 換 and 通 kanji entries.
Speaking of mnemonics, I'm not sure the ones in this book are that much better than the ones you can find elsewhere or make up yourself, etymologically correct or not.
天
The Real Kanji World: "A person with an enlarged head, aware of the heavens. Alternatively, 一 + 大: heaven is above (一) of man (大)." (not 上 and 人, mind you)
KanjiDamage: "一 + 大. To monotheists, there is only
one big god in heaven."

In this sense you are totally right. At the end of the day students should do whatever fits them better and find more useful themselves. The thing is the book I'm about to finish is something that I couldn't find before and I'd wish that existed. That's why I made it. It uses the power of mnemonics, just with some real (academic) source, thought to learn 2136 kanji at once in the most wisely organized manner I can think of. My guess is that there would be many people that would be benefited for the book. Some people happens to like RTK because it exists and have helped them, I think that The Real Kanji World can help as many or more people learning kanji.
The only problem I'm finding is that these complexities of the book that make it different are quite difficult to explain to the audience. Of course would be much straightforward to see the benefits if you have the book in front of your hands. Probably I should think of contracting some marketing experts, if only I had the resources haha.
I do agree though that the standard list of radicals could use some extension in order to make grouping (and therefore, learning) of kanji easier. In fact, the resource I learned from goes as far as making up its own: for example, it extracts the X from the likes of 渋, 楽 and 率 and pragmatically calls it the "sparkles" radical.
Yeah, the kangxi radicas have quite a bit of flaws, and even more when you deal with the shinjitai Japanese kanji.
