This is not really a question for Rosetta, it’s a question relating to Boinc Stats, but let’s have a go anyway.

The problem is not associated with your team, the rac you are looking at is personal to yourself and the processing that you’re doing.

If you log into BOINCstats.com and look at your detailed stats/last 60 days within BAM you’ll see that (taking Rosetta as an example) over the past few days you’ve been earning about 800 credits per day. If you go back a week you were getting about 1300 credits per day, indeed, on the 15th it was over 2000 credits. If you go back a month the figures are back down below 1000.

There are a couple of possibilities, have you changed the amount of time you’re using your computer or leaving it switched on? Does the pattern of credits match periods of hot and cold weather in your part of the world? Your I7-640LM is not the most powerful CPU and laptops can be prone to overheating if pushed hard which means that you could easily be throttling in warm weather.
