It's just possible that the jitter may be slightly higher, but I have no logging with which to collect statistics at the moment.  That will be more than I can get done before I go away.

Thanks.  Knowing it's in the same general sub-1ms range is enough to
advance the ball on Plain Jane.  Detailed stats may be interesting
later but there is no time pressure about that.
