The en-route rule
Keep only the pumps within 1.5 km of your road: 78, not 244. The cheapest you’d actually pass is €1.899/L, ~166.4 km in.
The 12 km decision-point circles counted 244 pumps at €2.049/L typical; the en-route corridor’s honest typical is €2.059/L — the off-route pumps had been flattering it.

206 pumps dropped as off-route — the dearest, €2.179/L, sat 4.11 km off your road. The old approach let it colour the picture.
It also found 40 pumps the 12 km checkpoints missed — stations you pass between the coarse 110 km-spaced checks that only a corridor catches.
