I looked up the formula on the wiki and when I build a single three-pointed star it works out exactly. I expected that multiple disconnected segments would contribute additively to power regeneration, but it seems this is not quite true. If you build a three-pointed star with arms of length 33 (100 blocks total), the total power generated is 48,959.4 as predicted by the formula on the wiki. However, if you then build a disconnected copy the total power increases to 97,718.7, which means it only increased by 48,759.3. What happened to the extra 200.1 e/sec? Or am I completely wrong about how disconnected power blocks combine?
