Just got the book from chin. The book introduces a great idea for open public to view horse racing in a systematical analytic way. Tools like mathematics, excel files are used to illustrate the ideas.
I haven't formally started yet, but has found the the author tried not to use difficult math to scare people off, instead he was trying to do those math in the excel, and thus hiding the joy of reading the book. :(
Also I am glad that he mentioned the Harville formula, which is a must in teaching his concepts, but on the other hand he didn't use the Henery's and Lo/Stern's model to illustrate further.
Some statistical test, chitest, pvalue, which is quite interesting (to me, a nonmath backgrounder). And this book will keep me busy for a while.

How far have you gone?

Read some of the chapters and slightly feel that the book is kind of... too much praise, too little explanation.
Chapter 1 / 2 / 3 refer to the methods used by the convention 馬迷, probably needless to me (I skipped quite lot) But a good point is that he was trying to quantify every parameters/conditions on the track.
Chapter 4 includes some stat., some little math. Chapter 5 / 6 I think are the main theme of the book, somewhat too 'operational', not enough explanation for an ordinary people to understand. And also the author expects reader find out the answer from the Excel themselves. Some readers may appreciate that if they don't like the maths, but it's just not adequate for people like me that love finding fact.
Chapter 8 is most fruitful so far, because he introduces (and describes) hedging and arbitrage on different pools. So it enlightens me and give a new way of thinking.

See, I told you so. ;D

I think next step I'll do the dirty job  to understand the excel by looking at those figures.

Any progress report for the last two months? ;)

I have stopped drilling into that book anymore, however, it leads me to the door of qualitative (computational) gambling, regardless of whether it takes me in or not.
But still this book is a good tutorial on the hedging. For example reducing the double pool into a win pool. Similarly reducing a placeQ pool to a place pool.
On the other hand, the 'expensive' book mentioned in this thread (http://chinman.com/index.php/topic,38.0.html) was a good reference in anytime. There are quite some parts of the book that I never go thro' yet. But it sound likes everyone is using the win odds to deduce the expected odds in the exotic pools.
Everything in the 'expensive' book and 計得精彩 point to one thing: there needs to have a database of past records to verify the correctness of the calculations. In fact this is a crucial step to build one to verify the any model deduced..

Yes, the database is a crucial part  a part that you have to have for further study but does not necessarily guarantee success.
One of the difficulties he has is the complexity and effort in maintaining that database on a ongoing basis.

Oh Chin, I brought the book with me tonite, but forgot to return it back to you. ( and also to wongyan, I have another book for you, holding for the whole night but also forgotten)

I've found a good link, I think it's very suitable for beginners if one finds interest. If I found this link months ago, then it must shorten my learning a lot. Don't know who is the author, but it's definitely useful.

Yes this page has been around for a very long time, explaining the basics of pari mutuel system.
Maybe the author copied some of the concepts from US, and tried to apply to HK, some of the formulas presented are wrong or in a strang format.
E.g. the very first formula on the page, it should be simply Odds=Si/S, instead of [(Si1)/S]+1. It's written in such strange format because the concept is translated from US style odds, where the odds is expressed as profit, instead of total return including the cost.
As a result of using US style odds, the expectation formula in the middle of the page is wrong if applied to HK odds.

Yes, agree. I do find it's quite uncomforted for the first few formulas by adding +1 to the odds.... which is very American style.

CX Wong just released the pdf version of his book.
You can email him to get the copy and the password. I am leaving a copy here for record.

Oh, thanks. Just emailed him.

English version is out on Amazon. I have my copy but have not start reading...

Will you? You've got and read the Chinese version already. :D

Days ago I read a few pages of this book at your office. I found the first few chapters interesting so I took it away. Will return later. ;D

Haha, I have the Eng version if you are interested...

Will return the book later today.
