For an expected RPM and distance from hub / rotation center, there is a
minimum tape width required.
For instance, if the engine cruise RPM is 2400 RPM, we look at the 2500
RPM line (next RPM greater) and we place the reflective tape 6 inches from
the center of the hub, the minimum tape length is 1". If the RPM is 2400 with
the tape 8 inches from the center of the hub, the minimum tape width required
would be 1.9 inches.

Insufficient tape width will cause engine RPM to fluctuate and provide erratic
readings.
