Obviously I used first and second in a reversed way in the two last paragraph.

Hi Philippe, please split this into two bug reports as only one issue should be filed in one bug report (see https://www.mediawiki.org/wiki/How_to_report_a_bug ).

Thanks, though not certain that we have it right.

To note that what we seem to have achieved is to support the display of the number of pages to be moved from proofread -> validated, rather than the total number of pages remaining to be validated. Nor does it account for where pages have not been started at all, so thirty "red linked" pages count as zero pages to be validated. Here I am looking at https://en.wikisource.org/w/index.php?title=Special%3AIndexPages&limit=500&key=&order=toValidate&sortascending=1

I would have thought the more realistic example of what we are seeking is

number of pages to be validated = total page count - (pages validated + pages without text)

I am guessing that we are looking to utilise this to identify works that we are trying to finish, so if we sort out the above would there also be a means to exclude pages where "to validate = 0" so we can set a permanent url to display those that need that last bit of effort to complete the works.

There seems to be a misunderstanding. To "validate" a page means exactly to move it from "proofread" to "validated" status. And this is what has been done, as this is what was asked. A possible application can be: I want to launch a "validation of the month" contest, and I need a list of books with lots of pages ready to be validated.

Now what you are asking is a different thing, that I would call "total number of pages remaining to be proofread and/or validated", i.e. pages where some kind of work (transcription, formatting, validation...) needs to be done. This looks easy to do, so I'll see if I can add a further option using your formula.

I'm not sure if it's possible to exclude books with 0 of such pages, but I'll look into it.

What has been produced is the ability to sort based on the number of pages in a work that are proofread. After that it is a matter of interpretative language, and I wasn't criticising more commenting, and the difference our technical jargon.

If someone asked me in book X how any pages are left to be validated, are they asking how many are proofread stage? or are they asking me how many are left to be moved to validated? In a 100 page work there are 10 pages edited, nine are validated and 1 proofread, and 90 are untouched, to say that a work has one page left to validated is a little weird.
