Soldato
It stops after 6 months (when he says CUT he means STOPPED not decreases).
Its all computerised and you will get a letter so it doesn't matter how many people are claiming.
On the day I got my letter I had a job offer so I was happy.
I know someone who was on it for a year, he couldnt get a job and ended up volunteering in a charity shop so he was more employable as one of the terms of staying on jobseekers.
The lad was a right goon and has no lifeskills etc though.
