Seems to be working quite well as of today. It was most likely a temporary issue. Give it another go!

I’ve been playing with cogmi for a week and it’s really cool what insights it’s giving me about performance. Usually I don’t even think about when to stop, but now there’s some data to focus on. It’s like keeping tabs on circardian rhythm but for brain performance.
