Well, to some degree teachers are always using their students as guinea pigs, and should always be doing this. However, the teacher should know enough to know what kinds of results they are getting from their experiments (and be capable of tweaking the experiment if the results the teacher desires are not actually being achieved). If a teacher has stopped experimenting altogether, or thinks they have nothing more to learn and try as a teacher, the teaching can be dead and even dangerous.
There are indeed some tools that become helpful and can/may be taught to most students in order to establish a firm musical ground. However, there will always be variations within this structure, and a good teacher should be able to tell the difference between a merely conscientious student, one whom proceeds with care and caution, vs. a person whom is lazy or obstinate and just doesn't care. In other words, each person will handle the information differently, and a good teacher will know how to help the student cope with the information in a way that is fit for the student.
Interestingly, as I look back on my own experiences, I can see clearly that I started developing ideas of my own that would lead me into my next experience. What I craved in one experience but felt like I was not getting, those cravings would seem to push me into a new experience. Honestly, it's those cravings that pushed me into this very forum and kept me coming back for more.
I can tell the difference between a teacher who is willing to listen to my concerns and appreciates them, vs. one who doesn't want to hear them because s/he fears her/his authority is being questioned. To me, the point of learning is to figure out one's own path, and there are bound to be questions !
In many ways, it's those questions which have led me. I can hardly imagine that those musicians whom have become the top artists and whom possess a deep and rich knowledge of their art, I can hardly imagine that these individuals "got there" by simply following directions and never asking a question about anything (even if the question were merely to themselves).
Part of that same curiosity though is a willingness to try new things. You yourself tried the suggestions you were given and got physical "feedback" from each thing. A good teacher will accept questions that may arise from a student having followed the directions they have been given. In the case of your first experiment, you were asked to try something that made you choke. At this point, you may have asked if this was an expected result to be getting ? And, if not, what could you be doing differently ? In the case with your latter experiment, at first you were not receiving physical feedback that you had expected and had you asked about the feedback you were getting, I assume you would have received guidance that would lead you on and into the desired results (which you ended up getting as you persisted).
This is all part of the package. A teacher is there as a sounding-board, to some extent. If they give a direction and expect you to do it, they better be prepared for the feedback they are getting in return -- that's how a teacher improves as a teacher.
Well, I am getting off on a tangent now and perhaps I will return later
