Please this is a PPL student being taught to fly visually.
I agree for IFR work sims do have there uses even in a PPL. But it has to be in a controlled lesson not a DIY teach yourself instrument flying.
For example getting the scan sorted before going for the instrument lesson.
Before you can objectively use a sim it needs to be taught and defined goals set.
It its a completely different kettle of fish an IFR trained pilot practising the tools of the trade to a PPL student teaching themselves bad habits.
