-** Delay values
-**
-** Notes: The parameter to the delay() function is ambiguous; it
-** purports to indicate a delay length, but that isn't really tied
-** to any real-world time measurement.
-**
-** On the original systems we used (dual 500MHz Intel P3 CPUs), each
-** "unit" was approximately one tenth of a second, so delay(10) would
-** delay for about one second.
-**
-** On the current machines (Intel Core i5-7500), delay(100) is about
-** 2.5 seconds, so each "unit" is roughly 0.025 seconds.
-**
-** Ultimately, just remember that THESE VALUES ARE APPROXIMATE AT BEST.
