I would consider a couple of pounds per week a slow leak.
I picked up some glass shards in my 51's rear tire on a long day ride. Came out of the cafe after lunch to find the bike standing nearly straight up after the rear went completely flat. I was about 50 miles from home with no tire repair kit so fix-a-flat was the answer.
Side note: three hardley f*cks were eating at the same cafe and we parked in the next slot by them. They left before us but not one of them came back in to tell us about the flat or that it was about to fall over (very windy day). :banghead
Yup it makes a mess:
