How many councillors does it take to change a light bulb?

The budget process at County Hall is, of course, all over bar the shouting. Decisions were taken by a handful of people, in secret, in Star Chambers, and will be rubber-stamped by the Cornwall Council Cabinet on Wednesday. Next month, the full council will devote the best part of a day to a completely pointless debate. If last year's budget debate is anything to go by, about 20 per cent of councillors won't even bother to turn up. So in an attempt to make it interesting, I invite comments on the following odds:

How many councillors will actually read the budget document?

Fewer than 10: evens
10-20: 6/4
20-60: 11/2
60-100: 33/1
100-122: 100/1
All 123: 500/1
