imagine this verticle cursor set overlayed to match you running compression waveform so that 0 on the cursors equals the first TDC peak on the running compression and 720 degrees equals the 2nd TDC peak on the running compression waveform , there is another TDC at 360 degrees as well but no pressure there .
at 180 degrees is BDC then at 540 degrees BDC again,
