Hi Richard, you are correct!
All of the other tech's where banded against the Medical Engineering Technicians profiles. In addition, the head of dept. a Clinical Scientist/ Medical Physicist, (Grade C*) got a band 8c (appealing).
From our point of view, it looks like it's
"MTO(x) + 3 = banding". Although it's clearly not like that across the country!
