Assume, in the following pictured Track, that Activity 50 is a "Patient Travels unattended," Activity and that Activity 51 is a, "Process" Activity. Essentially, 50 leads to 51. Now, notice that Activity 60 has Activity 51 as a Predecessor and that if the Patient's acuity isn't 4, the Patient is sent back to Activity 50 to do it all over again. Is this possible? Can a Patient really be sent back to a place they already occupy?
