I'm training at 23 cpm with 2wpm Effective Speed. do you think that is too slow? my plan is to increase the Effective Speed when I learn all of the letters.
You will get various advice . .
Mine is to go at as fast a speed as you can manage provided you are still making progress
or to put it another way
go as slow as you need to to still make progress
I think some people must allocate ( or expect ) a short period for learning morse
give up if they don't succeed quickly enough - which is of course their choice - probably 90% give up at least once
If you aim for a faster progress than your ability to learn provides
you will soon find you are not actually making much progress at all
On lesson 5 you will still be finding out how well it's all sinking in, so try a bit faster and see what happens
good luck with it all anyway . .
