Does Reflex frame-limiter limit every frame duration greater than the specific time？

[Defair]

For some reason, I need to limit every frame duration greater than the specific time, e.g. 16.66ms when DLSS-G is on. But what I see is, In some frames, Reflex does't sleep enough time so that make frame duation less than 16.66ms, e.g. 14.06ms. Did I misunderstand about Reflex frame-limiter's mechanism, will it sleep less time for frame pacing or reducing latency?

Another question, does reflex marker, e.g. simulation/submit/present influence the sleep time when I set Reflex frame-limiter to 16.66ms. I note Reflex SDK Integration Guide says in 2.1.2.3 that "latency timing information that is gathered by these time-related functions does influence the Reflex Low Latency mode logic timing in the driver when Boost mode is enabled".

1. How is "frame duration" measured? The minimum frame interval should guarantee that from sleep end to sleep end, it should be 16.66ms or more in your example. If "frame duration" is measured at another point on the pipeline then some frames can be shorter because each frame takes a different amount of time through each step of the pipeline.
2. The markers generally don't influence sleep time anymore. It definitely shouldn't in this example.
