Change input variables to compare different shots (see trajectory images and stats below).
ft	Height: Hitting height — For example, waist height is about 3-4 ft.
mph	Ball speed: speed into racquet. Typical speeds: 30 mph for groundstroke, 50 for serve return, 75 for volley, 0 for serving.
deg	Ball angle: angle (to court) of ball approach: 0 at top of bounce, negative if dropping, positive if rising.
rpm	Ball spin: into racquet — always positive (topspin) unless volleying then it can have positive or negative spin. Typical spin off court is 1000 (slice) - 6000 (heavy top) rpm.
mph	Racquet tip speed: Example: 80 pros FH, 65 college FH, 40 intermediate FH, or any speed depending on shot and player.
deg	Swing angle: racquet approach angle (measured from court). Upward swing positive; downward swing negative.
deg	Racquet tilt: forward tilt postive; backward tilt negative (tilt measured degrees from vertical).
in	Impact location: ball impact along center of racquet — 16 (throat), 19, 20, 21 (middle), 22, 23, 25 (tip) inches from butt
ft	Court location: where hitting occurs. Baseline=0, inside (negative like -10), outside (positive like 5).
