The Biofeedback Speed Wars are getting pretty funny. Virtually, all major equipment manufacturers claim that their equipment is the fastest and therefore the best. Our DOS programs are still generally faster as well. We feel CapScan and Biograph Windows programs are already fast enough for state of the art training effectiveness.
Few buyers know how to do accurate benchmarks, and are at the mercy of manufacturer's claims.
At least one manufacturer claims that there is zero delay between the sensing of the signal and the display. It seems according to information bandwidth theory there are absolute limitations to the speed of acquisition of signals no matter what kind of filter is being used. However, personally, I believe that the quality of the display, its look and feel, its accuracy, and the make up of the information the system is feeding back is more important than squeezing a few more ms off of an otherwise ineffectual display. That is the question. We do our best to deal with these questions in The Process.
