hi. in most tri-fit articles, i've seen knee angles listed at about 150 degrees with pedals at essentially 12 and 6 oclock. however, in mr cobb's slam descriptions, he states that he's using a knee angle of 45-50 degrees. is this simply the same angle as a 130-135 degree angle with a different reference point (ie, 180 degrees minus 130 degrees= 50) , or is this a different measurement, such as the angle with the pedals at 3 and 9 oclock? thanks,

ross
