    at least one pump carried by the housing and configured to fill a patient with fresh dialysate and drain spent dialysate from the patient; and

    a logic implementer configured in an ultrafiltration evaluation sequence to;

    (i) cause the at least one pump to pump fresh dialysate to the patient and drain spent dialysate from the patient after a first dwell time;

    (ii) determine, as a portion of the first spent dialysate, a first amount of ultrafiltrate (“

    UF”

    ) removed from the patient for the first dwell time;

    (iii) cause the at least one pump to pump fresh dialysate to the patient and drain spent dialysate from the patient after a second and different dwell time;

    (iv) determine, as a portion of the second spent dialysate, a second amount of UF removed from the patient for the second, different dwell time;
