| − | All of these speeds are sensible. The speed of the dental drill might seem excessive. But according to [https://sableindustriesinc.com/what-is-a-high-speed-handpiece-how-it-works-speed-more/ Sable Industries], a manufacturer of high-speed dental drills, they can run "at speeds of between 300,000 and 450,000 RPM." They squirt water as they rotate to cool the bits down, so they don't overheat.

| − | The precession setting refers to the {{w|precession of the equinoxes}}, which happens on a 26,000-year cycle that corresponds to the RPM rate shown. The average person does not need to adjust their telescope for such minor shifts, certainly not on a constant basis.{{cn}} This may be beneficial for scientists making precise measurements but they would have more powerful and dedicated tools to this end. For commercial use by the public, this would not be remotely necessary.

| − | The latter case is referenced in the title text, as the user's finger slipped and accidentally changed the tool to a higher speed setting while attempting to use the "sidereal telescope mount" option with an actual telescope, lauching it into the air at a {{w|hypersonic speed}}.

| − | The speeds labeled "record player" are intended to correspond to standard rotational speeds of {{w|Phonograph record|phonograph records}}. The intended playback speed standardized at 78 rpm (not 72 rpm as depicted in the comic) in the 1920s, with a diameter of 10 inches. The speed and size, as well as the required width of the groove encoding the music, dictated a playing time of about 3 1/2 minutes per side. Beginning in the late 1940s, records designed to be played back at 33 1/3 rpm (close enough to the 33 rpm in the comic) were produced, to allow longer play times (hence the LP designation, for "long play") on similar-sized records, which standardized on a 12 inch diameter. This was commonly used to release an "album" of songs, totaling about 22 minutes per side. Concurrently, an alternate format, 7 inch diameter records designed to be played at 45 rpm, was produced, allowing about 5 minutes per side. This was often used to release "singles" (a single song on each side of the record). The 33 1/3 and 45 rpm playback speeds supplanted 78 rpm, and remain the standards today.
