Have you ever had a lab test your compost for nutrients? Not all compost is the same certainly and what it is applied to isn't the same either in terms of need. Testing enables one to customize your compost to be a perfect match for the application.
In order to develop a perfect compost for a particular application, a soil test is invaluable. Over the years, I have developed what I consider a perfect compost for garden veggies with the help of soil tests to get the right mixture of legumes, hay, and cattle manure. I don't have to test it any longer because I already know if I mix it right, it will be perfect for my garden.
Here is my compost nutrient profile along with a nutrient density score of 95%. No N-P-K required when this is added to my garden soil.
