I understand the procedure and I understand the difficulty. I understand all of that. That would be built into the 4.5% that existed in the previous eight years. What I want to know is why it's doubled. You can tell me the numbers are bigger, but for that period of time, given the low inflation we've had, I'm having a great deal of difficulty.
You're outlining to me how difficult the process is. I accept that. I see that in the 4.5%, if one accepts that as an acceptable number, during that time period. What I find unacceptable is that it's now double that, so I want to hear why. Don't tell me how tough it is originally; we've already covered that. What's the doubling of the amount over the last few years? Why is that happening? It suggests to us something systemic.
