You'll have to give me a ring/email crystal for more info,
I try to get out for about 12 and have a decent break about 4 then back on it again from 5 till 7 in the winter, and 8 in the summer. It can sometimes get a bit soul destroying around 2 ish as the doors dont open much but I just power thru it and make the most of the contacts.
1 an hour is quite standard, I dont hang around too long at the door waiting for an answer, and pretty much run from house to house, I personally average 15-20 a day so about 2.5 an hour
