Interesting break-down of previous results. Some of the stats seem to go in our favour but no teams with form as bad as ours or Palace's have ever made the final! So Leicester v Palace final it is then. http://www.bbc.co.uk/sport/0/football/22437083 Mixed results for Brighton - the history of teams finishing fourth is terrible (no wins since '98) but they do have the best form which was a good omen...until 2005.
By the way, if you add those percentages together and halve them to cross-reference the historical performances of form vs. league position, the probability of promotion for each team is: Brighton 30% Watford 25% Palace 22.5% Leicester 22.5% Which of course tells us nothing.
