I have a total of about 7 CPD (HP11) crunching. Since about a month ago I'm experiencing much, much lower blockrate. Currently it's about one block per 2-3 days. Wondering who finds all those blocks?
Also I noticed (since day 0) that my machines often find a few blocks in a row (over 1-3 days) and then find nothing for days/weeks. I even had 3 blocks within a few hours a few times. Can anybody confirm, that it is more likely to find a block when a block has been found in the past hours? I can't believe this is pure luck.
Yes. They come in groups. It's not totally random. There are hidden parameters that are not well understood. In the hidden parameter space there is tide of "luck". I can only guess the parameters are related to network speed, performance of the whole network, and the condition of your peers who are network neighbors at the moment.
