Uh, but unless you emulate the entire universe you will always have external factors. If you emulate just the CPU, you will have external hardware (such as UART:s, video processors, etc), if you emulate those too, you'll still have user input, network traffic etc.

It's a synthetic CPU so the instruction timing and memory statistics are not extracted from the hardware CPU but computed in software so the hardware interrupts shouldn't be a factor.
