Hi Eric - I agree with you that the three sample lists should be included. I think that the number of pages will vary based on the website purpose, size and functions. It will be very difficult to say that you should evaluate at least 25 pages on every site. That said, here are the questions that I have: 1. Should we consider defining the number of pages in a sample based different scenarios or types of websites? 2. To defined size, do we need to talk about the number of pages or could we define it like you have done with the three sample lists and let the evaluator determine from those lists how many pages should be reviewed?

The discussion varied between 6 and 5000... How many pages should we have in a sample to be replicable and at the same time achievable in terms of time and money? In the updated version of the Methodology that will be online in the coming days I added: - the three sample lists that should be included into an evaluation (core, task-based and random). If we just take one of every resource named there, we have at least 25 pages.
