Pranav's discus and Yugan's Discus

Pranav has the discus resting on his fingers and he is able to swing the discus with it facing down. The discus came off with the index finger and he span it clockwise. His body leaned back before the throw, his angle of release was about 40 to 45 degrees. 

The discus was resting on the finger pads of the finger, I am able to swing the discus with it facing down. The discus came off the index and span in a clockwise direction but body was not leaned back before the throw, and angle of release was about 40 to 45 degrees. I think I could have leaned back before the throw so I could have more momentum and the discus could have span further.
