Unlike product design and creation, mones have a special attribute that makes it different from conventional results testing.
It is biological and it’s effects are in the bounds of nature. All testing of mones are therefore subjected to “finely tailored suit” whereby it is best tested individualy.
Although the effects of certain molecules are documented
and produce similar reactions to different people, the main issue resides in the amount of doses each individual needs in order to achieve either the minimum or maximum benefit.
Take care of those two ends and know your overdose, and you can use the molecule itself well enough within expected results.
Purpose:
It is in our nature to understand things better with illustrations. Put them together with words and it makes things easier to understand. Will do more of this if it gets good feedback. Primarily made for people starting out.
P.S Updated for further explanation 
(Thank 1Alpha)
the Minimum Effective Dose (MED);
Where by the results of the particular mix/molecule/instant line spray shows CONSISTANTLY minimal/self/small results in others/self. In the case of your example, your MED for IS will be ISX2.
Maximum Effective Dose (MaED);
Where by results of particular mix/molecule/instant line spray shows results CONSISTANTLY in a huge beneficial way in a others/self.
Example of this would be Spaceland or IJ, where the effects are still noticable, beneficial in DOCUMENTED effects with relation to what the main molecule is supposed to do and people get the full impact of it.
Overdose(OD)
Where by your mone signature is NOT documented by people around you because it becomes un-natural. Example would be extremely high doses of -none.
So that leaves the question, where does your "ISx 4 to 6 to get some much better results than if I just went with ISx2…"belong to? They belong in the average category in-between MED and MaED. For the sake of simplicity I would classify it as controlled doses dependent on situations and environments.
Definition of HIGH RATE
How than does each individual establish on MED, MaED and OD?
By using the theory: The Law of large Numbers
whereby;
“In probability theory, the law of large numbers (LLN) is a theorem that describes the result of performing the same experiment a large number of times. According to the law, the average of the results obtained from a large number of trials should be close to the expected value, and will tend to become closer as more trials are performed.”
Once a person continues to use daily and record down the results of each molecule/mix/instant line testing, the results of each SAME application becomes more and more consistent and predictable.
The keyword here is CONSISTENCY. When you have achieved a consistent and reasonable enough basis to expect from the extreme ends of the doses, you will more or less understand and fully KNOW how to use the molecule towards your desired tailored effect.
The crux of this issue is to establish, through the theory of the law of large numbers, 3 points of measured doses that gives you MED, MaED and OD. When you establish this 3 main doses, you more or less are able to master the use for that particular mix/instant line/molecule.
