[Shqiptar] Rregulli i 85%

# The 85% Rule: Why Getting Everything Right (Or Wrong) Kills Learning [Albanian content summary] Psychologist Robert Björk's research shows learning is optimized at 85% accuracy. Material learned at this level is retained 50-70% longer than at 95%. Too easy (95%) and brain treats it as unimportant. Too hard (55%) and frustration kills engagement. At 85%, learners experience optimal challenge called "desirable difficulty." Error detection activates dopamine, strengthening memory encoding. Neuroimaging shows prefrontal cortex fully engaged. Amal's HLR adaptive system continuously monitors accuracy and adjusts difficulty, maintaining each child in optimal 85% zone.
