All very interesting but we need to make a thread on how to get this all set up (HRV, ARP) without paying the retail combined price of over $30k. This could probably be done for <$3k for experimental purposes.
TopCat, what hardware do you use?
Jamirok, how long do your sessions last in general? 1hr? Do you just use the OmegaWave to check at the end? I imagine it would take quite a long time to do multiple ARP attempts while checking each time with an HRV analysis. Hope this makes sense.
