Time To Recognize / TTR

To acheive CW fluency, after we are familiar with all the characters, we work to reduce our "time to recognize" (TTR). This utility will help you to measure your time to recognize words.

The initial setting is 20 wpm with standard word spacing. At 20 wpm, the standard space between words is 420 milliseconds. After the word is sent, the word is flashed on the screen after a 420 millisecond delay. As an example, you may double the space between words by changing the word spacing to 2. Similarly, at 12 wpm, the standard word spacing provides 700 milliseconds for recognition.

You may also wish to run this without revealing the word sent by unchecking that option.
