For me it was not controversial, just imperfect. The perfect diagnostic would learn in one pass what the student has already mastered and not leave them with study material they can already answer at 100%.

I didn't think anything was seriously wrong, just wrong enough to be annoying for the first few days because I wasn't learning much and the system is rigid and zero trust — I have no way to tell it I understand except by hard proof.

It's also a balancing act, though. Under-estimating a student's ability on purpose might frustrate them a little but offer a small confidence boost while they're still learning the system and finding a daily rhythm. Over-estimating could make them feel stupid and intimidated and drive them to drop out early.
