By the same token, do you have info on older forecasts? Freddy Hutter tracks these, Lahèrrere won the blue prize for 2008, predicting 85 mb/d with 85.5 mb/d actual, prediction from 1997. FWIW, as they say.

Would be interesting as well to see the MASE applied to each class of forecasting, or price calls.

Here's the forecasts ranked by MASE score; also threw in peak dates - had to leave out date ranges owing to lack of ability/time:

Thanks!

It's a nice way to show the results, I'm going to keep the idea.

can someone test if there is a statistically significant correlation between assumed/predicted peak date and accuracy -- it seems that the 10 best performing models all peak in the next 5 years, while 10 out of the worst 15 predict a peak 20 or more years from now.
