Incomplete target delineation example

In recent CT-base target delineation, marginal failure is major concern. But 'CFIMT' is theoretically, such problem is lower than IMRT. I challenge to make incomplete target delineation for whole neck irradiation virtually. And I asked for a lay person to plan using 'template' about this PTV. This try was done without using MLC.
