There is a time and a place for everything.
What you are promoting is meddling/getting into your own chefs head WHILE he is mixing the ingredients.
The difference is the chef has all the ingredients in front of him and has done the same play 1000 times back to back.
In the park, the ingredients are forever changing, the scenario is forever changing, and you KNOW the coach can't handle the pressure.
In the meantime you are promoting the addition of new ingredients to the soup.
Not a good recipe for success.
