So a bit over 300ms overall latency, assuming the last two digits are hundredths of seconds? Of which some will be caused by the camera and computer/monitor, rather than the Spark itself.

We were doing some testing with ours this morning.

d500>hdmi>spark>ethernet>1900ACS>5Ghz wireless>dell laptop(not new - 5yrs old?)>HDMI>TV

As far as we could tell the total delay was around 0.5-0.6 seconds (showing a timer on screen and counting aloud). Of course it feels like 3 seconds... we have not tested with a full ethernet connection yet to see the differences. I guess we should zoom in and take a photo and check more accurately...

Not good enough for IMAG, but for showing around a venue where people can't directly see the event while looking at the screen - prob ok. Unsure what dissonance the lack of sync on sound will cause.

We had the same result, 500 ms.
