Such information surely exists somewhere, but it is of no use for you.
Under "normal conditions", you can expect upwards of a dozen DPCs and upwards of 1,000 interrupts per second. These do not respect your time slices, they occur when they occur. Which means, on the average, you can expect 15-16 interrupts within a time slice.
Also, scheduling does not strictly go quantum by quantum. The scheduler under present Windows versions will normally let a thread run for 2 quantums, but may change its opinion in the middle if some external condition changes (for example, if an event object is signalled).
Insofar, even if you know that you still have so and so many nanoseconds left, whatever you think you know might not be true at all.
