I had this theory and I wanted to write about it so others can also be able to book vaccination appointment through CoWin app for yourself, friends and families. But I was reluctant to do so before as I needed to test-run it successfully myself. After booking two slots in one day and another two on the day followed, I can confirm this method works. However this method will not guarantee you a slot as you are competing against a multitude. In order to book an appointment slot I would suggest you to use a laptop or desktop as navigating through these devices are faster than a cell phone.
