I don't care what you say ... higher speed does not necessarily
translate to better communication. In fact, as I demonstrated here* and
as countless 160m ops will attest, lower speed is typically more
intelligible under conditions of low S/N ratio:

And as others here have said, you dramatically cut down your pool of
likely respondents if you insist on operating above 45 WPM in a contest,
and if you're sending your call three times in a row in a pileup you're
just an unnecessary part of the QRM.

Some prefer the challenge of isolating a CW signal in order to decode it. They
use filtering. Eliminating interference is difficult. Interference comes from
numerous sources.
An exchange of call signs is the desired result in a pile up or contest
exchange.
Sending at a lower speed does not improve the probability of accomplishing that
communication goal.
CW speed is a critical part of the communication equation. An operator sending
at 15 wpm has 1/3 the rate of success than one who sends at 45 wpm.
The later sends his call 3 times to only one for the slower station. Simple
math. It might sound like bragging. A thinking person will understand how
critical speed is to a CW operator. Some rely upon filtering. That only gets
you so far with the goal.
I like the improved success that comes adding speed. Bragging ? I like to
succeed. I use every tool I have.
Just my way of competing. Some can do it better than others.
