Also, perfumer's apprentice offers a basic cologne accord (which you can buy), for comparison purposes:
These measurements are in grams and would make 1000 grams of concentrate.

To handle the trace components, you would just pre-dilute and adjust the formula.
You can also do this by drops as a learning exercise.
