The numbers on each transistor is relative to the 1x nMOS transistor in the inverter. The Cin of inverter is 3x.

If we think (inverter + PTL) as one stage gate to get logical effort, there is one branch at node X. At node A1, branch effort cannot be included because we considered (inverter + PTL) as one stage gate. snow eraser
