Although I don't think I degust things as a general rule, I must say there have been times.
Surely, when we degust our meals (etc.), we can often find benefit in doing so, if we are paying enough attention to things.
The items we degust can become somewhat 'different' in some ways, since the practice lends itself to having the power to alter our opinions about some of the things we degust.
Do YOU typically degust your meals (etc.)?
