Here is virtually the same set of tests as yesterday. "Rap City Top 10"
is one hour shown at 1 and 5. "The New Detectives" is one hour shown at
2pm only.
Single record Rap City is padded from 12:57 to 2:10:
--- print list start ---
Title - Subtitle Chan ChID Day Start End S C I T N Pri
Rap City Top 10 - "Black College To 27 1027 01 12:57-14:10 1 1 1 S 1 3
Adding New Detectives drops the padding in between:
Rap City Top 10 - "Black College To 27 1027 01 12:57-14:00 1 1 1 S 1 3
The New Detectives - "Murderous Att 25 1025 01 14:00-15:10 1 1 1 S 1 3
Endoffset +1 for Rap City and there is a hard conflict.
Rap City Top 10 - "Black College To 27 1027 01 12:57-14:11 1 1 1 S 1 3
The New Detectives - "Murderous Att 25 1025 01 13:57-15:10 1 0 0 S C 3
Changing Rap City to Channel chooses the later showing:
Rap City Top 10 - "Black College To 27 1027 01 12:57-14:11 1 0 0 C L 0
The New Detectives - "Murderous Att 25 1025 01 13:57-15:10 1 1 1 S 1 3
Rap City Top 10 - "Black College To 27 1027 01 16:57-18:11 1 1 1 C 1 0
Change the endoffset back and it still chooses the later showing
to make room for soft time:
Rap City Top 10 - "Black College To 27 1027 01 12:57-14:10 1 0 0 C L 0
The New Detectives - "Murderous Att 25 1025 01 13:57-15:10 1 1 1 S 1 3
Rap City Top 10 - "Black College To 27 1027 01 16:57-18:10 1 1 1 C 1 0
Change the endoffset to -11 and it still chooses the later showing
to make room for all soft time:
Rap City Top 10 - "Black College To 27 1027 01 12:57-13:59 1 0 0 C L 0
The New Detectives - "Murderous Att 25 1025 01 13:57-15:10 1 1 1 S 1 3
Rap City Top 10 - "Black College To 27 1027 01 16:57-17:59 1 1 1 C 1 0
Change Rap City to Single and priority +1 (total 4). There is room for
either softend of RC or softstart of ND but not both. It chooses the
softend for RC because it is higher priority:
Rap City Top 10 - "Black College To 27 1027 01 12:57-13:59 1 1 1 S 1 4
The New Detectives - "Murderous Att 25 1025 01 14:00-15:10 1 1 1 S 1 3
Rap City priority -1 prefers the softstart for New Detectives:
Rap City Top 10 - "Black College To 27 1027 01 12:57-13:49 1 1 1 S 1 2
The New Detectives - "Murderous Att 25 1025 01 13:57-15:10 1 1 1 S 1 3
