Test script:

on({id: 'squeezeboxrpc.0.Players.CCA_EssZimmer.state', change: 'ne'}, function(Obj) {
    log('New state: ' + ['PAUSE', 'PLAY', 'STOP'][Obj.state.val]);
})
on({id: 'squeezeboxrpc.0.Players.CCA_EssZimmer.Artist', change: 'ne'}, function(Obj) {
    log('Artist changed');
})

Resulting log:

yes. the adapter receives minimum information every 950 ms.
every 10 seconds LMS sends some additional information.
the adapter has to write this information into data points for each grouped player (synchronized player).

The comparison and data management requires additional performance in the adapter and iobroker (1.reading the previous data, 2.comparing the data and 3.writing the data 4.updating the internal memory for next comparison).

Therefore all data is written as it is sent by the LMS (so only 1+3)
