I'm not sure you're understanding really how the system works, which is exactly what I was pointing out in my statement. I never said "guaranteed" - I said "stable". There is ALWAYS risk of losing the customer and the government can terminate at any time for almost any reason. But if you perform, then you can maintain the same customer for a decade or more.
This is how the system works and it works this way for a reason. There is more accountability in the government market than people realize - moreso than in most commercial transactions even.
