Maybe SQ had a policy of pinning up in their crew room a graph showing fuel consumption for each month, with the captains name alongside it? I know JQ did because my name was on it. SE Asia again, but those monthly pin-ups in the crew room sure did get attention. It then became a competition to see who could get the lowest reading. Check captains included. It was a subliminal farce to post those statistics and most of us ignored it.
