|
|
|
5
|
|
|
6 AAAA.BBB.CC.DD.EE
|
|
|
7
|
|
|
8 AAAA: Relative runtime of the last deco engine invocation, in ms,
|
|
633
|
9 signed value: positive numbers: overrun on target runtime
|
|
628
|
10 negative numbers: unused time budget
|
|
|
11
|
|
|
12 BBB: longest runtime found, in ms
|
|
|
13
|
|
|
14 CC: Calculation phase in which the longest runtime occurred, see table below
|
|
|
15
|
|
|
16 DD: Number of deco engine invocations required to complete the last normal plan
|
|
|
17
|
|
633
|
18 EE: as above, but for alternative plan (cave return or CCR bailout or OC fTTS plan)
