[BUG]: E2ELantency calculation

[ViGeng]

Package version

3.0.0-pre.7

Environment

* OS:Windows11
* Unity version: 22.3LTS

Steps To Reproduce

1. run E2ELatency
2. see the latency value
3. look into the code

Expected Behavior

Hello, I am a bit confusing about the calculation of latency.
When we look into the code, the update method should be called frequently as defined by targetFrameRate
I timestamped this method and it shows as I expected.
Then as the figure below, the current latency calculation should be similar to the 1000/fps.
however, the produced value is not as ecpected.

So nor of them run as I expected. I am not sure how the latency should behave.

Thanks for any information and help!

Anything else?
