By the way, I still have problems with longer characters now and then or
combinations of certain characters. I had an awful time trying to copy
a
call sign in a contest that began with SH5 (3 dots, 4 dots, 5 dots).
and you dare claim it must be doable by everyone else

same here!

i have trouble with high speed B, 6, 1, J. however, you can create a
practice regimen that focuses on these.

a trick for contests might be using a spectrograph or MFJ viewer. good
luck.
