You have disregarded the word "axial" (along the long axis, ie rotating the IR emitter without altering its beam axis). Besides, I do not believe you have conducted this experiment to have made the observations; and even if you had, the experimental method is flawed because if you had conducted the same experiment with the remote held "vertically" for test 1 the result is likely to have been the same.
The Scientific Method involves not only postulating a hypothesis and then testing it by experiment, but also publishing the exact method of those experiments and the results for other independent researchers to criticise and verify.
I do not agree that "hypothesis" is synonymous with "conjecture".
