Who are "The Ultimate Fighters"?

If you search the blogosphere you'll find enough mma blogs to keep you entertained right through the working day. Some offer news and gossip about scheduled bouts, most give reports on previous cards and plenty just give their opinions about who they think will win upcoming bouts. Here are the aggregated results, which I hope are self-explanatory:

	Vs TUF1	Vs TUF2	Vs TUF3	Vs TUF4	Vs TUF5
TUF1	(12)	0.33 (6)	0.5 (2)	1.0 (9)	- (0)
TUF2	0.67 (6)	(8)	0.8 (5)	0.67 (3)	1.0 (1)
TUF3	0.5 (2)	0.2 (5)	(7)	0.25 (4)	- (0)
TUF4	0 (9)	0.33 (3)	0.75 (4)	(10)	- (0)
TUF5	- (0)	0 (1)	- (0)	- (0)	(4)

	UFC Record	UFC Record (minus TUFx fights)	Vs all TUF	UFC Record (minus all TUF fights)
TUF1	0.649 (65)	0.717 (53)	0.706 (17)	0.722 (36)
TUF2	0.565 (60)	0.596 (52)	0.733 (15)	0.541 (37)
TUF3	0.462 (32)	0.440 (25)	0.273 (11)	0.571 (14)
TUF4	0.420 (78)	0.397 (68)	0.25 (16)	0.442 (52)
TUF5	0.652 (19)	0.733 (15)	0 (1)	0.786 (14)

A number of interesting points become apparent:

• So far TUF5 has the best fighter record - although this is a small sample and I expect these figures to change in the coming months as the TUF5 fighters face more difficult challenges.
• Prior to TUF5, the winning percentage of TUF fighters had decreased steadily from the first season to the fourth (against all fighters except those on the same season of the show).
• Fighters from TUF1 and TUF2 have far superior records against other TUF fighters than those fighters from TUF3 and TUF4.
• TUF1 season fighters have beaten TUF4 fighters on all 9 occasions they have fought.

More thoughts and in-depth analysis later.
