What jitter do you get with the "latency" test running at the same periods? What are the distributions of the jitters? All only around 4.5 or 8.5 ms, or are they spread over a far wider range than with 5 ms cycles? I can't look into this soon, but it has high priority for time I will have test equipment in reach again!
