What is the proper way to calculate or determine the amount of time between words (the key up of the last character of one word to the key down of the first character of the next word) when using Farnsworth timing?
When using the answered time for 18 WPM characters sent at 5 WPM overall, will this calculated time result in exactly 5 canonical "words" sent every minute? Or more? Or less?
How do hand key and paddle operators determine this inter-word delay time in actual over-the-air practice?
