Read the equation
Subtracts request time from response time. It measures elapsed response latency when the timestamps are comparable and the response event is clearly defined.
Terms & definitions
The recovered passage does not supply a separate symbol table. Read the source context for the notation used in this version; familiar letters may carry different meanings in other builds.
How it works
Read RT as the quantity being defined or updated by this relation.
Substitute the source-defined variables or recorded values and follow the displayed arithmetic and indexing exactly.
Use this version’s variable definitions and update order. The same symbol may be assigned a different meaning in another build.
Assumptions & limits
Source recovery establishes that the expression appears in this record. Its mathematical validity, implementation behavior, and interpretation must be assessed separately. See the linked source and research notes for the checks available for this version.

1. Response Time:
RT = t_{\text{resp}} - t_{\text{req}}
2. Success Ratio:
SR = \frac{\text{successful ops}}{\text{total ops}}
3. Cost:
\text{Cost}_7 = a_7 RT + b_7 (1-SR)
