Bill-san,
Thank you always for calling me at AWT. :)
The method by the CW Academy of the CWops is ¡°Sound Copy¡± in my naming.
¡°Sound Copy¡± is very effective at earlier stage of mastering HEAD COPY as I experienced.
However, if a longer spelling word comes, my ¡°Sound Copy¡± takes longer decoding time and then missing the next word beginning.
So I started letter-by-letter decoding in my head that I call is ¡°Letter Copy¡±.
Actually my ¡°Letter Copy¡± does some multi letter copy such as ¡°ER¡± of ¡°EVER¡± and intermittently switching to ¡°Word Copy¡± such as ¡°BEEN¡± and other often heard words.
What I understand here is time-shorter letters such as ¡°E¡± and ¡°I¡± tend to tern my ¡°Letter Copy¡± to ¡°Multi Letter Copy¡± and ¡°Word Copy¡±.
My ¡°Letter Copy¡± doesn¡¯t work well at slower 15WPM and faster than 20WPM by different reasons.
Slower ¡°Letter Copy¡± may lose decoded letters in the brain and at faster ¡°Letter Copy¡± decode cannot catch up to the speed.
Both issues are caused by the performance of so called Working Memory of the brain, I suppose.
Working Memory retains usually 5 +/- 2 items and only for a few seconds but works with some other tasks like Morse code decoding.
It is said that Working Memory degrades when aged like 50yo and this degrade may cause ADHD or dementia.
I hope my HEAD COPY training may avoid those brain disease. hihi
