What it measures
Both runs transcribed the same 13-minute recording on the same CPU, according to the project's benchmark table.
How it is calculated
418 seconds / 102 seconds = 4.1
What it does not show
A single benchmark run by the project that makes faster-whisper, using int8 precision for it and fp32 for openai/whisper. The project's own headline figure of up to 4 times is the more cautious number to quote.
