MotoGP Season 2011, 2012 attendance figures

Hi,

I've watched all MotoGP races from this season to find out the attendance figures on Sundays. I've found nearly all figures but there are 3 races where I can't find any information of spectators - Grand Prix of Qatar, UK and Germany. I don't know when where these figures published (probably during Moto2 races).
Does someone have these attendance figures please?

I would also like to know all attendance figures from season 2011 but I can't find them. I would like to know how many fans visited each race and then compare spectators between these 2 seasons.

Could you please help me?
