Sounds about right for an airline training department.
Experience airline pilots usually don’t give a toss on how to calculate the density altitude. Most probably they forgot how to. As long as you remember higher temperature = higher density altitude. That’s good enough. I still remember tho but never I had to use it unless for CPL/ATPL exams back in the days.
