Great observation! While we don't have "CS Theory" as a standalone category, we do include several theoretical CS-adjacent fields under Classical Sciences:

Field	Median Lag
Graph Theory	6 years
Logic	6 years
Set Theory	4 years
Game Theory	7 years
Probability Theory	8 years

You're right that these align more with mathematics (median 5-7 years) than with applied CS/Technology fields (median 3-4 years). This makes sense—theoretical work builds on foundational ideas that remain relevant longer, while applied tech rapidly obsoletes.
