The judges points were awarded like this:

Jorgie & Matt: 7
Chemmy & Sean: 6
Andy A & Maria: 5
Charlene & Matthew: 4
Heidi & Andrei: 3
Andy W & Vicky: 2
Mark & Frankie: 1

From this we can infer that Mark must have finished at least third in order to be safe presuming Andy A finished last with the public
Charlene and Andy W must have also finished at least one place above Heidi
Chemmy must have received more votes than Andy A

Therefore I predict:
Jorgie & Matt: 7 + 6 = 13
Chemmy & Sean: 6 + 4 = 10
Andy A & Maria: 5 + 1 = 6
Charlene & Matthew: 4 + 3 = 7
Heidi & Andrei: 3 + 2 = 5
Andy W & Vicky: 2 + 7 = 9
Mark & Frankie: 1 + 5 = 6

Heidi has the lowest overall total and Mark survives over Andy A as the greater public vote is used to separate a tie.

Jorgie & Matt: 7 + 7 = 14
Chemmy & Sean: 6 + 3 = 9
Andy W & Vicky: 2 + 6 = 8
Charlene & Matthew: 4 + 4 = 8
Mark & Frankie: 1 + 5 = 6

Andy A & Maria: 5 + 1 = 6
Heidi & Andrei: 3 + 2 = 5

Bit late from me but I think it may have gone:

Jorgie
Mark
Chemmy
Andy W
Charlene
Heidi
Andy

in the public vote, cba to do it combined
