A discussion on OCR benchmark saturation: @soldni notes most benchmarks saturate well before 100% and points to VikParuchuri's analysis of where the missing 10% of OCR accuracy went. @srchvrs concludes that complex outputs are hard to measure precisely, and while OCR can be more accurate than many benchmarks, handwriting recognition likely can't reach that ceiling.
