Hello there again, you made a decent post, however, anyone could get some of the info from the internet. Even a person with little knowledge about martial art is aware that distraction in a fight could cause a lot. So, if you wanna balance within this professional advice, and review, you need to tell us instances where you used those tricks/moves/stance and describe how they worked for you. Perhaps, you messed up on some part, and you got kicked. The review should have an element of Personal interaction or experience.

A product can be seen as something produced by labor or effort or the result of an act or a process. So a piece of professional advice is given as a result of effort from a professional. That advice can go a long way to help anyone that needs it. If such advice is tapped and used by anyone, it becomes a useful product. However, any professional advice that would be given should be in-depth and not peripherals (based on your perspective of course).

Cheers!
