You’re right, and your post needs to be seen more. Learn Morse audibly, not visually. Whenever I see someone post about these charts it instantly tells me that they don’t actually use Morse.

Learning Morse visually means you have to decode it with more steps:

hear code --> visualise the sound --> decode to letter

Decoding by ear is the fastest way, and is the way that Morse operators decode it (eventually you just hear words).

hear code --> decode to letter.
