Nah, it didn't work for me. Years ago I was sucked in by what I actually believed was a cornering course, but it was in effect a track day. My poor Ruby (previous ST13) was revving the whole time between corners, trying to act like a racing bike. Can't recommend it at all. When you get a chance, have a look at the tacho in the video- it's red-lining much of the time.
No doubt about the rider- he does well rounding up the field.
