Yes, show them to us. We crave data.

@jb honestly, scenarios are so small that even if the odd one takes much longer than normal, there is a very nice predictability to the rate at which they get done because of the volume of them flowing through. I’m not a statistician but I expect there’s a term for that. I have graphs. Want to see them?

We’ve long said that one could use customer tests/acceptance tests/examples to measure progress by tracking trends in the number that pass. This in contrast to programmer/design/technical tests, which must always pass 100%.

I wonder, though, about people trying to do this, and expecting the calendar time to pass an example to converge to the mean. I don’t think it will. Have you seen anyone fall into this trap? What did you tell them?
