I don't disagree with your observation, although like the pyjamas, it has prompted me to wonder why they don't just use a mileage chart to determine PJ provisioning or BoB / snacks. Mileage is the underlying variable in the stage length, so attempting to average the variance out of it and using that as the deciding factor is oddly opaque. But perhaps that's what they want.
