rotation of the rotor
I was wrong by saying that the rotor rotates one and two thirds to two revolutions each e-shaft revolution.
I now realize that a rotor turning two thirds of a revolution on a eccentric bearing that orbits the journal each rotation has a rotation that cannot exceed the journals revolutions.

The rotors do indeed rotate at 2/3rds the rate of the eccentric shaft....BUT in the opposite direction, netting a 1/3rd forward rate! This means that it takes 1080 degrees of eccentric shaft rotation to turn the rotor 360 degrees (completing 3 cycles). Thus, every turn of the eccentric shaft nets one cycle per rotor. HOWEVER, while the rotor *rotates* at one third of the forward rate of the e-shaft, it still *orbits* at full speed on the journal.

The rotors do indeed rotate at 2/3rds the rate of the eccentric shaft, creating the appearance of a 1/3rd backward rate! This means that it takes 1080 degrees of eccentric shaft rotation to turn the rotor 720 degrees. The loss of 360 degrees puts the rotor in phase and completing 3 cycles. Thus, every turn of the eccentric shaft nets one cycle per rotor. HOWEVER, while the rotor *rotates* at two thirds of the forward rate of the e-shaft, it still *orbits* at full speed on the journal.
SIMPLE REVISED DIRECTIONS TO PROVE THIS POINT
Place a rotor on the back housing with the stationary gear. put the E-shaft through the rotor and position the rotor at the end of the compression stroke.
Make mark one in the middle of the rotor and another on the E-shaft at the same location. Now number two and three counterclockwise in the center of the trailing surfaces.
Turn the e-shaft one half revolution clockwise and the e-shaft mark will then line up with number 3. Turn the e-shaft another one half revolution and the e-shaft mark will then line up with number 2. #2 is now in position to fire.
Note that this all takes place with clockwise motion.
This confirms the fact that the rotor rotates at two thirds the journal revolutions while it is in orbit around the journal at full speed.

Fessing up to mistake #1 is a great start. : )
He didn't answer my question of his statement about the cooling oil inside the rotor getting so HOT that it turns into a SOLID. : (
