I have been asked about the performance of regular participants to the CET competition over the years. I have gone back to 2010 and calculated the average prediction error for those members who have participated every year since 2010. I ignored 2009, which was the first year I ran the competition (because there were too few participants - sorry Saint). I have allowed one missed year otherwise it would be a very short list. For those who did not make it to the end of one year I have used the average prediction error of all the others in the table for that specific year (this figures are highlighted in orange).

Here is the table - there are 18 people listed. No surprise that Darren S is comfortably in the lead. This lead will be extended when the 2018 results are added.

Let's hope there are more than 18 in the table next time you post it.

I even made 11th place but I can’t imagine what I was doing in 2012 that stopped me predicting that year.   

Good luck to all for 2019!  Not you though Darren, you don’t need luck!

Many thanks for this analysis GW. I'm pleased to feature as high as I do (for now), but not surprised to be a fair way off Darren! Maybe 2019 will be my year. Nah, probably not.

Happy New Year all!

Many thanks GW, I thought I was a lot worse than that!! Well on the slippery slope in recent times🙈😀

What a year it’s been though!  Probably the most exciting since we started these CET threads, not just for the competition but for watching records toppling!  I’ve lost track of all the records set throughout the year but I’d be surprised if it hasn’t been a record year for records!  

Thank you all for the friendly banter and thank you SC, Gavin and GW for all the technical data you provide.

Biggest New Year’s Honour goes to GW of course for running these threads!   (Can’t find the ‘clapping hands’ smilie).

Cheers - Thanks. Feel well pleased. I bet though I've only hit it bang on a couple of times since I've been in the competition. . I have to admit I intially thought I was taking a big gamble with that one. Talk about mild December.

Hey!  Well done HT!  And I think that means the amazing Darren’s done it again, although Steve has given him a run for his money  and an exciting finish.

I reckon in all the time I've been in this competition I've only hit it bang on once or twice. Anyway - Its a great competition and it's good fun as well.

Although I was wrong betting you it would settle bang in between us at 6c!  Well done!  Now you’re on a roll, let’s see if you can keep it up!    

Annual CET competition - Final table

No surprise to see Darren S topping the table this year and winning the gold medal. He has been in first place since April and never outside the top three all year. So big congratulations to Darren.

The winning figure of 6.69C is the third best since the competition started in 2009. In fact it is not Darren's best result as he finished with 6.25C when winning the competition for the first time in 2014. Whether Idle's record of 5.99C remains intact.

Shoeshoe sneaks into second place, recording a highest position in the table this year. Gusty finishes in third. The top three were well clear of the rest.

Some big movers further down the top 10 including Devonian up five to fifth. Hungry Tiger climbed 10 to 15th after winning the December competition.

sussex snow magnet and Hippydave also recorded their highest position of the year with several others equalling their highest position from earlier in the year.

Despite winning the competition to predict the CET for the whole of 2018 (see separate thread), springsunshine takes the wooden spoon in the cumulative monthly competition.

The tables below show each person's position in the table for every month of the year (with the highest position shown in red) and also the monthly prediction errors for each person. A figure highlighted in orange denotes a missed prediction where the error was calculated using the formula set down in the competition rules. A figure in yellow denotes an error of 0.50C or less.

I have also included a figure for the root mean squared error in addition to the absolute error. This alternative calculation penalises large errors to a greater extent (due to the squared part of the formula). So consistently low predictions are the way to get a low figure under this method rather than say several exactly correct predictions but also with a few quite large errors. Interestingly under this method Snowshoe would have won due to having no errors above 1C.

Finally here is the updated table I posted yesterday that now includes the 2018 data. This shows the average prediction error for the last 10 years for those members who have been in the competition for the whole of that period (with a maximum of one missed year which is indicated in orange).
