I've never used DNA Painter because I figured out that the chance of it being of any practical value was out of proportion to the amount of time it would take. The same applies to most other techniques which are not included in the DNA Masterclass.
People often write to tell me that I should publicise this or that site or technique, but when I ask for examples of how it has helped them in practice the evidence is usually lacking, or else the same results could have been achieved more simply and more quickly by following the strategies in the Masterclass.
I believe in keeping things simple, and using my time wisely - the Masterclasses are designed to achieve this.
