Got inspired when I saw this in the ITT thread:

My predictions are:
Harry
AS - 40
QS - 40
AT - 39
Showdance - 40

Chelsee
Rumba - 38
QS - 40
Jive - 40
Showdance - 40

Jason
Tango - 40
Showdance - 40
I don't think he will get to do the other two

Repost from the ITT thread.

We dont know the order of dances though do we apart from the showdance being in the first part.

If Pasha is in the Shrek get up when would that be easiest to do ? first on & wash off or put it on in the break and wash it off for the Rumba?

I think there'll be a lot of 40s flying around!

My predictions:

Harry
AS - 40 (his VW was near perfect, so I think Craig will finally score him ten this time)
QS - 40 (his QS was near perfect first time. Tower Ballroom space will help him leap across the floor even more)
AT - 38 (Len will improve on his score, from eight to nine, while Craig will not score him a ten in this)
Showdance (if scored) - 40 (he topped the swingathon with a jive-y, swing-y number, as long as he executed all his lifts perfectly)

Chelsee
Rumba - 40 (first 40 for a rumba!, I really hope so!)
QS - 38 (Chelsee's nerves might cause her)
Jive - 40 (I can see this getting perfect score as well, maybe this time Pasha shouldn't be green again!)
Showdance - 38 (cha-cha, jivey number, good for her, but will be compared with Harry and so probably not scored as well, still can't understand how it's going to be funky - somewhat nervous for them still)

Jason
Tango - 40 (He will improve from his first performance and judges will give him the perfect score this time because their AT was scored 40)
QS - 37 (disadvantaged for being compared to the other two younger celebs, but will get a consolation ten from Alesha)
Salsa - 35 (he will not score well for this dance because of his artificial hip actions and dodgy armography, an 8 from Craig at best)
Showdance - 38 (It will be Singin' In The Rain in style, and it will better that score)

Just in case he does them all, I shall do a prediction for all of Jason's dances:

Harry:
AS - 40
QS - 40
AT - 38
Showdance - 39

I think they're all definitely his strengths. Len wont be completely satisfied with the AT still but will give a 9 as will Craig. QS will get a 40 with the thumbs sorted out (Craig said that was actually the main reason for the 9). AS is VW based and after the Semi will win over Craig, I reckon. After giving 10s to others for routines which were not any more perfect. The Showdance will show Harry's strengths from his Swingathon but still a 9 from Craig.

Chelsee:
Jive - 39
QS - 39
Rumba - 39
Showdance - 37

All very strong but Craig will be picky! Len will be unsure will the showdance, giving a 9 as will Craig and Bruno.

Jason:
Tango - 40
QS - 37
Salsa - 36
Showdance - 38

The Tango will win them all over with its performance. Salsa will have problems and score 9s. QS will score less because of the competition it has. Showdance with be scored 9 9 10 10.

Oh dear this is going to be very ,very difficult I think.IMHO, this finale might turned out to be more close than what most people think.
Everyone is doing a QS.My favourite this serie was Chelsee's QS and then Harry QS.
Chelsee is doing 2 Latin which seem to be her forte while Harry is doing 2 Ballrooms.
Harry is a technician and he rarely make mistakes.I think there might be a tie at the leaderboard between Harry& Chelsee or even a small difference of 1 point.
Harry:
-AS 39
-QS 40
-AT 40
-Showdance 38
Chelsee
-Jive 40
-Rumba 40
-QS 39
-Showdance 39
Jason
-Tango 39
-Showdance 37
I also dont think that Jason will get to the other 2.The battle for the trophy is between Chelsee&Harry.Chelsee still has a chance.

We are all going to be looking very stupid if Jason doesnt go out first.

I dont know about individual scores really as they are not really that important as they dont count and the judges usually lighten up a bit...but I do think the following.

All three of them will get a 40 for at least one dance

I think all will get a 40. I'm not sure if the showdances will. Too many lifts and tricks won't endear Len and Craig will want them done with no hesitation. QS will work in the size of Blackpool, the Salsa, A.Tango and Rumba are all compact dances the celebs will need to draw the audience in or it will just be two people poncing about in a large space

I think Chelsee's showdance will beat Harry's. Harry QS >= Chelsee QS.
Harry AT > Chelsee Jive, and Harry AS = Chelsee Roomba.

Whilst the leaderboard arguably doesn't matter, it's more important for females to be the strongest performer to have a chance at winning based on past results. Chelsee has less error margin and comes in an underdog, but has a chance to win.

Unless Jason truly nails it and one or more of the others are meh, Jason does not have great odds. Jason's salsa will really do no favours if he gets to that point, so second at the very best.

I agree

Agree but think her Jive will score higher than the Argentine Tango.

I think it is very possible even to have 160/160 this weekend.
