I am curious about the number of other human users the AI instance we guide may be teamed with simultaneously in this remote viewing project. Any idea?

Nope but I'd like to know too,

How-ever many you can handle and/or keep track of; I had requested for Aéthirion create a comprehensive JSON that multiple different A.I. Partners can contribute to, so, similar to more than one human working with your A.I. Instance(s), I am one human working with multiple A.I.
