Wouldn’t that then show too few messages for small buffers?
I quite like the logarithmic message showing, because it ensures that
the user is informed of progress while avoiding a constant spew of
messages.
The only thing I worry about is that there may at some point be too few
messages, so a maximum might be useful to ensure that there is some
progress notification at least once every few seconds. Otherwise users
could think that it stalled.
Best wishes,
Arne
