I probably do understand what this is already, but it's a bit of NLP jargon that I am unsure of...
...so I thought I'd just start a thread about it and ask everyone the following:

What is calibration?
What does calibration mean to you?
What is the point of calibration?
How do you learn it?
How do you teach it?
How do you do it in the real world without third party input?
etc etc etc....

Look forward to some interesting replies
