There is an old saying about that most British of obsessions - the weather - that goes "the only thing that is predictable about the British weather is its unpredictability."
You could certainly apply the same adage to the WTA Tour which has enjoyed the type of rollercoaster year that might have led to even the shrewdest tennis gambler filing for bankruptcy.
At times, the quality on show has been as up-and-down as the results, but the true joy in following women's tennis this season has rested in the fact that you never quite know what is going to happen next.
When Dominika Cibulkova won the WTA Moscow event last weekend she amazingly became the 33rd different winner on the WTA Tour this season - and that is out of only 55 events.
Cibulkova also became the sixth first time winner on the Tour this year, while we live in a WTA World where someone like Roberta Vinci can win three titles in such a mixed-up season and still only be ranked 22nd in the world.
With all that in mind, it is great that we are going to have such an unpredictable finish to such an unpredictable season and this week's WTA Championship in Istanbul really has the feel of a tournament that any player can win.
The bookmakers, so normally the leader in forecasting things, seem to be as confused as everyone else as to who might lift the title.
Some of them have Petra Kvitova as the favourite, while others have gone for Victoria Azarenka.
Caroline Woznicaki - who has won the most titles this season and is ranked number one in the world - is only fourth favourite with some bookmakers.
Na Li is considered the complete outsider with all the bookmakers but still as short as 14/1 with some firms.
It is a completely eclectic tournament of styles and nationalities - if you included the two alternates (Marion Bartoli and Andrea Petkovic) - you have nine nationalities represented out of the 10 participants.
There is also an intriguing sub plot to follow too with Wozniacki and Sharapova fighting for number one in the world rankings (technically, although highly unlikely, even Kvitova or Azarenka can achieve this feat).
And oh yes - there is also the small matter of the prize money on offer with the winner in line to receive $1,750,000 if they win all three of their round robin matches, which is akin to winning a Grand Slam.
All in all, it should be an unpredictable feast of tennis over the next week, and we will certainly be glued to all the action in Istanbul.
Tramlines prediction on who will win? We haven't a clue!
