As VK is an intentional tool, connection with VK and clear intention matters most.
Along with rotations there are other ways like holding VK, just touching VK, holding VK in your palm like we pray, imagine VK so Rotations can be of standard speed, slow and little fast ( not much)
More than rotation, your intention and right energy for the specified work matters.
If you don't have much time for rotations then place the request in the suggested way, and leave VK on side to send energy for next 30 minutes.
Rotations are preferred as it keeps you connected at a better level.
Bigger the quantity, more the rotation. So if 500 ml needs 20 rotations then 2 l quantity of water / other liquid needs more rotations, . Rotate approximately 40 … To 50 roataions.
One more thing to practice is that when ever a content (water here) is full of required energy then energy gives you a repulsion. As you practice VK more and more you can start observing that repulsion too.
