Vision target location

[Pretzel]

There should be enough at least for the horizontal strip.
The horizontal one "begins 5 ft. 8 in. above the FIELD carpet, is centered over the LOW GOAL, and consists of a panel with one (1) 4 in. wide, 1 ft. 11 ½ in. long strip of retro-reflective material (3M 8830 Silver Marking Film) adhered
horizontally"

This tells you that it is centered above the 2 ft. 8 1/2 in low goal, which is placed in the very corner of the field (its outside edge is in line with the outside edge of the alliance station). Centering a 1 ft 11 1/2 in piece of tape over that low goal would then require you to be .375 ft from the wall (subtract the width of the tape from the width of the goal then divide by two). This translates to 4.5 in from the edge of the alliance station where the high goals are mounted and 5 ft 8 in above the ground, as stated in the manual.

As to the vertically oriented static vision target:
"The static VISION TARGET is mounted such that half is behind the polycarbonate sheet above the LOW GOAL and half is behind the acrylic panel of the PLAYER STATION. It uses vertical reflectors which are located above the inside edge of the LOW GOAL. The vertical reflector consists of a 4 in. wide, 2 ft. 8 in. tall stripe of retro-reflective material bordered by 2 in. wide black gaffers tape on the left and right sides. The vertical reflectors begin 3 ft. 1 ½ in. above the FIELD carpet."

The way I interpret this while looking at the picture is that the center of that reflective tape should be at the inside edge of the low goal. To double check it though you could see what the measurement is from the edge of the alliance station to the start of the acrylic since it states that it is mounted such that half of it is on the polycarb above the low goal and half of it is on the acrylic in front of the drivers.
