Bumper Numbers?

[Saberbot]

I found a PDF of the manual here.

According to R35

[R35] Teams shall display their team number on the Bumpers in four locations at approximately 90° intervals
around the perimeter of the Robot. The numerals must be at least 4 in. high, at least ¾ in. in stroke
width, and be either white in color or outlined in white. Team numbers must be clearly visible from a
distance of not less than 100 ft, so that judges, referees, and announcers can easily identify competing
Robots.

Any color you want, as long as you have a white outline and meet the size and placement requirements.

Neat.

It doesn't really specify how thick of an outline, though.. Which is troubling because we could technically make either a 1mm outline or a 1 cm outline with a huge difference.
