A nice little improvement would be to get the \"Time to Completion\" a bit more accurate, and also the CPU Benchmarking. (Are the two linked in any way?)

One model I am running says it has 2090 hours to go, but from the graphics, you can see the Number of Time-Steps in the model and the Seconds/TS, so that calculation isn\'t that complicated. CPDN says I have 2090hrs to go...my maths and calculater says 1593!!!

The other model is the same sort of error, circa 20%.
CPDN says 2678hrs to go, but I reckon it has 2212 hours running at the current 1.9s/TS.

It\'s BOINC that\'s doing the calc\'s, and the latest versions have been optimised to be more accurate for short projects, whereas previously, (the 4.* versions), it was the other way around.
As there are lots more of them than the 3 climate projects, we lose out.

Just as well that cpdn doesn\'t use the benchmarks. :)
DIY is definitely the way to go with time-to-completion.
