Ron, I think you are going down the same path I did on the 64 bit baseline last year. In sbitx_gtk.c we made the tweak like yours which leaves Farhans code and the polling rate undisturbed for all current and future modes, except for new special treatment (more frequent polling) for MODE_CW and CWR.
I like Gordon's comment about the Shannon limit, but there is no limit on how much people will complain when you clip off one of their dits or dahs!
I originally started to go through all the CW related stuff between modem_poll and key_poll to see if it should be streamlined but Farhans original code seems pretty good.
if (ticks % 20 == 0)
modem_poll(mode_id(get_field("r1:mode")->value));
else
{
// calling modem_poll every 20 ticks isn't enough to keep up with a fast
// straight key, so now we go on _every_ tick in MODE_CW or MODE_CWR
if ((mode_id(get_field("r1:mode")->value)) == MODE_CW ||
(mode_id(get_field("r1:mode")->value)) == MODE_CWR)
modem_poll(mode_id(get_field("r1:mode")->value));
}
and over here in sbitx_gtk
if (ticks % 20 == 0 || cw_tx_now ){
modem_poll(mode_id(get_field("r1:mode")->value));
cw_tx_now = 0;
}
