Dear @Dave ji, you are very right in your perception but please do not incline to your conception. As per the manual, effects are surely same, you can only identify it when you know it rightly. Please understand, suppose you know Chocolate is very sweet and you tend to try a dark chocolate. Your perception says it is sweet and following that you conceive that is should be sweet as honey. Now, Dark Chocolates are less sweet and with a tinch of bitterness. So when you eat the Chocolate, you get disappointed because your mind has already conceived it as sweet as honey.
Using VK, please leave your conceptions, because now you are dwelling in the world of energies which is generally unknown to commoners. Reason being the same, I asked you the question in my above post. I presume that you know about Chakras and spiritual experiences, but please wait till you have one. Anulom-Vilom is a Paranayam of Yoga. It is the process which supplies Prana to your body system. But we are not so elevated as yet to know if we are getting a such and such amount of oxygen or our Chakras are being activated. Moreover, exercises are a daily routine, so why should be expect a miracle to happen by just doing it once? Leaving aside, our conceptions, when we practice the process through VK, again and again, we start feeling the effects and they are magical. Question yourself that Did your physiotherapist healed your cervical in one day? Why do we require to have medicines for 5 days in case of Viral fever? and do we get the effect of a Yoga exercise, if we are a novice in Yoga?
I am sure you will find satisfactory results when you will stop looking for results even before you are conversant to the process.
