Yes, Sir, I can assure Mrs. Chow that we'll be keeping
statistics from now on over the next few years, and I'm sure
the trend will have established after a few years' time.
But in practice we've adopted a wastage rate of 9 per cent to
10 per cent over the years in forecasting future demands, and
this figure is quite close to the overall figure which we
have in mind.`
