Bleed Radiators in Autumn, Not Mid-Winter Shiver

Bleed Radiators in Autumn, Not Mid-Winter Shiver sounds like a micro-optimization until you are on Line 1 when the carriage smells faintly of hotpot from someone's lunch box.

Try this once: write the rule on your phone lock screen for three days. If it survives, it is yours.

Not gospel.
