The logging wasn't put in to show the conditions under which the 
ergonomics kicked in, it was put in to show CDS users that it had kicked in.

So if you think it should be logged under additional conditions, that is 
fine, but please do not replace the existing logging.

Unfortunately there is no nice way to log the same information under 
multiple tags.

Thanks,
David
