1) 3/50 - normal
Fresh UVP#3 Collodion mixed from A/B stock about 5 days ago (available from http://uvphotographics.com/ - excellent and super fast collodion, but I still can't get rid of those darn lighter areas you see on top of each plate... very weird, but that's a topic for more experimentation and possibly another future blog entry)
95% Grain Alcohol - 15ml
EDIT: Someone asked if overdevelopment fog wipes off. NO WAY - this stuff is deep there. It really does look totally different from all the other types of fog possible...
EDIT 2: Here's a good exercise that you may want to do to determine what is the absolute MAXIMUM amount of development time that your developer will allow. It'll take only an hour or less and it'll be helpful - believe me.
Coat and sensitize a plate and then develop it for just a little longer than you normally do. Keep careful track of time in developer. Look for the signs of golden-looking crystals. Don't see them? Do another plate for just a little longer. Do a few plates until you start seeing those crystals. Again - they usually appear first in the center of the plate where collodion first came in contact with the plate during your pour.
So say you start seeing then at 25sec (most people use more concentrated developer than I do their usual development times are 15-20sec). That means you can PUSH development to about say 22-23sec without ill effects.
Make sure to note the temperature of your developer - hotter developer will work fast, colder will be slower, kinda obvious, but I thought I'd mention that.
