Attention Residue / Friction Spike
Optimal Flow Threshold
Why this happens (Crenshaw, 2021 & Adeoye): Every context transition incurs a double cost: Orientation Latency (remembering where you left off) and Attention Residue (your working memory remaining partially anchored in the previous problem). When task slicing drops below 30 minutes, overhead can devour over 30% of actual productive hours while multiplying operational slips.
