“I just read your book and found it fascinating. Thanks.

On calibrated estimates, once experts are calibrated, do they stay calibrated?
Or do you repeat every time that you are beginning a project or making an estimate.

I’m just thinking in a corporate setting – do you just do it once for a group of people that you may want estimates for or would you do it before each project. Do it annually?

What has been your experience on how long people stay calibrated?
