Schedule.buffer.EPG
This is another end time buffer, similar to Schedule.buffer.end. However this buffer is variable and proportional to the item's duration as given by the EPG.
E.g:
If duration=30 minutes, and Schedule.buffer.end=15 and Schedule.buffer.EPG=10, then total end time buffer = 15 + 10x30/60 = 20 minutes.
If duration=120 minutes, and Schedule.buffer.end=15 and Schedule.buffer.EPG=10, then total end time buffer = 15 + 10x120/60 = 35 minutes.
