Hmmmmm,
EPR decreases with increasing airspeed, doesn't it? On Classic with P&W -7, if EPR was set to 1.44 TO thrust at 80 kias, then at VR this would have reduced to 1.42 (= G/A Thrust). If thrust was advanced to 1.44 at VR, an 02 overboost was being applied. Actual thrust increases with Ram effect, however................
