I would make the intent you are creating a WAV file from mention the water. Then it should work.
Like for focus, do “The glass of water I am intending is charged with focus. Thank you. So be it.”
If you want to do a paragraph or page of intentions, it is best to use the WAV Converter to convert a TXT file to WAV. For WAV Converter, the time specified is the actual length of the final WAV.
I agree. 10 mins is good. There is extremely expensive water programming software that says it can do it in 20 seconds. I don’t know how.
