Visually and mentally fatiguing means you’re doing it right, IMO.
I generally only run classifiers in practice twice for that reason. I treat them as a test / proof of concept rather than practice.
You passed the test with flying colors. Best to stop after two successful runs otherwise you burn in bad runs and sloppy runs.
Celebrate the successes on the tests but don’t get greedy.
Fatigue is real and should be respected.
So consider stopping earlier and convert to partial drills that augment the concepts you’re working on.
All IMO.
