Thank you Ralph, I havn't actually compensated for dry down at all. I just started reading your book and will use the f/stop table for this and other things the next session. And I must say this book looks like exactly what I have been looking for, finally ennough detail so I can really understand what is going on. (Being the neophyte I am, I suppose I will see the light at the third reading though :-) ) I allso understand I need a much better evaluation light than today. Now, its just a 40w bulb in the ceiling...
I have been told that long exposure (overnight) to water is hard on the emulsion of papers, and not recommended.
I've actually had the the emulsion slip off of some papers if kept in water overnight. Why risk all the hard work you just did?
Depends on the paper. Some are only 4%, others 8%. You should do your own tests.

I've always used a bank of 4-4foot daylight balanced tubes about 7 feet away and never had a problem, because I know how different situations will look on the prints and I pay attention.
It depends on the paper. I've done jobs and forgot to take them out of the wash...after 14 hours, the emulsion came off (Zone VI MG fiber paper). Other papers, like Ektalure, same amount of time, or more, and no problem. Best is to wash them just after printing. Using a product like PermaWash will only take you 5 minutes first wash, 5 minutes 2nd wash, 5 minutes final wash. Before you know it, you will be done.

Your stating that it doesn't matter what light you use to view your print when wet. Sorry to disagree but that it poppycock!
It , as Ralph explained is very important so as that you can evaluate your print in the darkroom when wet. . I see it as a very important triangle. Printing paper in tray>brightness of light>distance of light from print in tray.......
All three have their importance in the evaluation of the final look of the finished print/drydown. This is why it is important to test.
For instance... My dry down for Ilford MG4 FB matt and WT semmi matt is 20%. That is whats set in my R,H.Designs Timer, and it works for me. So you tell me who is wrong. Ralph, Me?... The answer is neither. It is because we have both tested and our 'LIGHT' source is different, along with the distance in relation to the print.
I use a 60 watt daylight bulb about 80cm to a meter from the print.... If I moved it further away I would need less dry down factor set in my timer....Replace the bulb to a 100 watt and I would need more...Replace the paper, well, I would start all over again. You see, all three play there own important part.
So 'LIGHT' is important, would you not agree Alexis.
P.S Please take this as it was meant, that is as a valid argument and not a personal attack. If I were to remove one word, it would be 'Poppycock' the rest would stay.
Depends on the paper.
That's why it's called a rule-of-thumb. 1/12 stop (5%) works quite nicely for most papers. If you experience less or more, change the above figure. The point is, it's easy to compensate for.
Alexis wrote again, among other things:
It depends on the paper.
Photography has rather complex dependencies. One author once said: In photography everything depends on everything else.
Nevertheless, it is helpful to establish and communicate some general guidelines, always realizing that they always influenced by the materials or equipment used.
The statement 'It depends' is true for almost every note in this forum.
I'm sure the many words of advice given above are best heeded, ie dont do it! On the other (lucky, perhaps) hand I have on occasion left prints sitting in water all night long because I was just too tired to wait for the wash. They suffered no ill effects other than being delicate, but its certainly not something I would make a habit of.
