I've used 30/45 seconds scans on my wife (who has metastatic breast cancer) and have documented that she noticed a sensation within 20-seconds on most of the frequencies termed 'hits' but, on some frequencies, of longer scan periods (90-seconds), she noticed a sensation after 60 seconds has expired. However, I have also noted that on a pulse frequency of 37Hz the time of initial sensation is much shorter.
