XF4 - Male
XF5- Female
XF6- Male?? Joe? Olly? Danyl?

The Farm:

Series 1- Male
Series 2- Male

Also the winners of the 3rd series of these are considered the best and that series (Series 3) was the most watched series. Kerry's victory was seen by about 13m, Kate's victory was watched by 10m.
And this isnt in the pattern because they are males but BG3, was the most watched of their series, with around 18m watching the finale.

So its safe to say Series 3 of relaity tv shows rate the best.
Something random I found!
