Where it comes from
Our calculation from other figures in the trainer’s notes:

Show the working
- Python OLS GM = a + b*t on 's four points, then six with /7: 4-pt a+b = 0.312, se via t(2) = 4.30 gives 0.26-0.36
- 6-pt a+b = 0.317, CI 0.28-0.35
- Q1 pair (t 0.663->0.675, GM 0.398->0.413) slope +1.24
