So is the desired location of peak pressure on a rotary about 14 deg= ATDC as it is in a conventional engine?

Perhaps 8 to 10 = degrees or more, after TDC. Ignition advance at the RPM =0Awhere the engine= is used is based on developing maximum cylinder pressure at the =0Aideal c= rank angle (leverage) for best HP. That angle is a function of engine =0Ade= sign and unaffected by RPM.
