I think it would turn into a chore and you wouldn't get much else done! All the planning, travel etc. Then sometimes I 've had something planned in advance but just haven't felt like it on the day. I have done four in a week (Wednesday, Friday, Saturday and Sunday) but they were all women I had seen before, two at a flat close to where I lived and the third in Soho, so I had a nice Sunday afternoon in London with some sex as well. There wasn't really much to plan.
I'd consider a punt a day for a week as some sort of challenge as I like silly punting stats but I can't see it ever happening.
