I'll get on top of the sketches for you, and I'll include any information I have -- when I turned them, who they were before (if I know), what their habits have been like since, last known locations.
There isn't a standard rate, no. Basically as fast as you can drain someone. I did about two per night. You could do more if you didn't wait for them to wake up after (usually takes a few hours). Not all vampires care about reproducing, but with their populations being low here, some of them are pretty motivated.
