    Run 3061, 3062 kin Q3_i40
    Data rate=320 Hz, but Dead Time calculation is 9-10%.
    Earlier runs at this rate had only 1% deadtime.
    T9 is a 30 Hz trigger, which does not have a scaler, but
    DAQ assumes at 30 Hz rate in computation of Deadtime.
    Run 3061 replay shows NO T9 events (contrast with e.g. 3051).

    Probably T9 is accidentally disconnected.
