I did my first 8 flushes with 7-10 days in between. It's not recommended, but my body just sort of demanded it. A week after flush I'd get this nagging feeling that it's time to flush again, so I did. After 8th flush my body told me it's better to wait two weeks until next. I am now flushing only once a month. Some of those close-spaced flushes were very productive and some produced hardly anything visible, but I felt good either way.
I would encourage you to listen to your body when spacing the flushes.
Remember, everyone is different.
