He is absolutely right about these numbers being data points. And he is also right that the more we get, the easier it is to make good decisions. It is simply a realistic and pragmatic view of what these numbers represent.
I have adopted a similar view towards food and eating in general. I always want to enjoy my meal, but sometimes diabetes demands food when that may not be my first choice. I still must eat. Because, food is medicine and I must take the appropriate medication in the appropriate dosage at the appropriate times. This has helped me an awful lot in sticking with effective eating habits.
In my opinion, my meter, my diet, insulin and exercise create the equation I use in response to my meter and in order to eat to my advantage. This keeps my surprise meter readings to a minimum.
