nice stats there

Wow, I didn't realise Jim today would be the 3rd worst swap ever! I suppose most of the swaps are between low value reds and blues, though, so Jim's swap was actually one of the more risky ones!

Mmm, but if he'd pulled it off and swapped the £250 for £20k, it would have been the best swap ever! (Well, the best ever swap right at the end of the game...obviously Ned's and Mike's from last week were even better.)

For some reason I didn't view Fin's and Julia's anywhere near as bad as most of the other ones, because they still went home with good amounts!

Yeah, Fin had already had his worst moment with the big gamble at the 5-box stage going wrong, and Julia's was basically just a choice between two quite similar amounts.

I guess you could do it in percentage terms, but then the likes of Nick would be up at the top for swapping away a mere £100 for 1p and a place in the Hall of Fame!

You could also argue that Connell's swap was a bad one, as he swapped away £10,000 for 1p.

Perhaps do it by "distance between amounts on the board"? Although then swapping £750 for 1p would be seen as worse than swapping £250k for £3k, which I don't think would be quite right...

Anyway, whichever way you look at it, I think we're all agreed that Barbara's was the worst.

OK then, top 10 worst swaps by percentage of box amount given away:

1. Connell - 99.9999% (£10,000 for 1p)
2. Nick - 99.99% (£100 for 1p)
3. Gary - 99.97% (£3,000 for £1)
4. Barbara - 99% (£100,000 for £1,000)
5. Jim (Dec 06) - 98.75% (£20,000 for £250)
6. Irene - 98% (£250 for £5)
7. John G - 96% (£250 for £10)
8. Matt - 90% (£50,000 for £5,000)
9. Jim R - 83.33% (£3,000 for £500)
10. Fin - 50% (£20,000 for £10,000)

Again, not ideal as it ranks people who swapped peanuts for smaller peanuts, ahead of those who gave away life-changing amounts!
