Yes, Marv, that is how my 107 Kts was arrived at on the day I did the test. I defy a Lancair 320/360 pilot to hold that speed whilst hand flying the airplane and doing problem analysis, checking for a landing spot, trying a restart, yelling help, etc. AOA is a great device and will get you the right number, but it won't make much difference if yu try to "streeeeeeech" the glide.
