Final comments
 
 
- There is no such thing as an "accurate" 
 estimate	any more than it is possible to forecast "accurate" prices
  on
 tomorrow's stock market
 - and that's only 24 hours away !
- All estimates are subject to the vagaries of future uncertainty
- Therefore the issue is "credibility" and "reliability"
 - not accuracy
 
- Estimates are not budgets, they need converting !
