Please read the six lines following the piece you quoted.....and you will answer your own question
How tall does the pencil look when held vertically, with your arm vertically above your head?
(worth pointing out that what I'm calling 'drop' is actually the vector resulting from the force/time/acceleration etc of gravity -just easier to illustrate the example by grouping them into 'easy' language -'drop'. Sticking with easy language, for a vertical shot, the drop is straight back down the path of the bullet (in vector terms it will, therefore be a decceleration.)
The only way to reduce the effect of gravity is to get in a space ship
