$60 is at the end of power cycle on graph.
If you count After TDC it will be at 180* ATDC
If you count Before TDC it will be at 540* BTDC[720-180]
SO the math will be after TDC counts from 0 to 720.
Before TDC will be [720 - degrees after TDC]
0* is at the start of power cycle and 720* is at the end of compression cycle. That should be norm for timing chart.
What that bothers you may be that the EoiT target is inverted.
From left to right
0-720 degress = $80- $00 target value in table
