The attached picture shows the diagnostics for someone I was playing with. The audio interface latency is 6.0 ms (mine was the same) and the internet latency is 14.5 ms. These add to 20.5 ms and yet the total latency is showing as 51 ms. The numbers were fairly steady. Even if you add in the jitter (should you?) the sum only comes to 27 ms. Would you expect the sum of individual latencies to add up to the total? In other sessions with different people I find they usually do.
Subjectively we could detect no effect of any latency on our ability to keep together. It felt just like playing in the same room. In a session with someone in Rhode Island (I am near London) we had a total latency of 80 ms of which 60 was internet. It was impossible to keep together with that amount of latency. One of us had to lead and the other to try to keep with that. Not very satisfactory. If 80 ms is almost unplayable it seems unlikely that 51 ms should be perfect. I am therefore wondering if the reported 51 ms is wrong and that it was actually nearer the 20 ms sum of interface and internet latencies.
On a separate point I notice that Frame Size is 10 ms and red. What causes that and can I change anything? We each have the Frame parameter set to 5 ms. Is that the same thing?
