The floor angle markings for the front HRS angle cameras have been touched up to increase legibility. All angle and half-angles between 12 and 56 for the right arm and between 12 and 70 for the left arm have been marked, except for 12.5, 13.5, 14.5, 15, and 15.5 on the left because the camera is currently ih the way.
Additionally the two rear cameras used for measuring the HRS angles have been adjusted to clearly show both the scales and the floor.
Also, the labels on the webcam snapshots are backwards, as the cameras labeled front are actually the back, and vice versa.
