Heel on pedals, Inseam x 0.883, 109% of inseam, inseam (in CM) less 10cm, 25 degree at the knee...all produce results that are within 15mm of each other for me. All of these methods are good for finding a starting point, but in the end you will need to explore a bit to find the saddle height that helps you produce the most power, keeps parts from getting numb, and (most importantly) is the most comfortable.
Don't rush the process, it takes time.
