Well for Einstein it took about 6 months, and the first Seti 100k came pretty fast because I had alot more machines at my diposition back then but the second 100k came real slow as I stopped crunching for Seti for quite some time. Now I'm on Predictor, just started it, hope to get 100k on that one too. My long term goal is to get that milestone on all the projects I joined like LHC and Climate Prediction. I like to crunch for different projects, I get bored after awhile, I need variety! To me, the Boinc total score is the most important stat, so no matter what project I crunch for, in the end it's all for the Overclockers.com team...
