Your 1). In what way do the figures and photo stills not match? How are the figures misleading?
Your 2). In what respects are the text and photo stills not complementary?
Your 3). My view is that Blake's use of phrases such as "feels like" and "seems as though" is to help the reader learn his swing. However, when he states his swing theory he does not use those phrases.
Assuming Blake's right elbow is not as far forward at impact as he claimed, what do you believe is the significance of this observation? Do you think he was mistaken in his belief that his swing was powered solely by his legs? Jim
