I have done some numbers crunching, calculating running orders basically given the amount of points for each slot as for instance 2/15 = 0.13 would be the second dance of 15, 15/15 = 1 would be pimp slot. The worst slots are 2 (worst) and then 3-5. Opening dance is about a 6th place (out of 15) early but usually a decent dance so I added extra points to reflect that. By those calculations, indeed Pete is being benefited but almost as much as he is, is Anita. If anyone is getting a raw deal in terms of running order/scoring (Ie they are dancing well by the judges scores but not getting the good spots) is mostly Georgia and Kellie in less degree,
Pete 3.57
Anita 3.33
Jamelia 2.88
Katie 2.86
Helen 2.85
Carol 2.56
Jay 2.55
Jeremy 2.38
Ainsley 2.26
Kellie 2.01
Daniel 1.69
Georgia 1.58
Kirsty 1.25
Anthony 1.14
Iwan 1.11
