I don't know where your source come from but in the last update they reduce it. And like I say ED it more then just exploring but when you do it explore uss in the run and you will be surprise.The most efficient way to explore in terms of cr/hour is to only target class G stars and up, look for earth-likes and gas-giants, and ignore everything else. Open galaxy map and look for your next jump, repeat.
Hopefully FD will take a look at exploration and increase the value of surface scans, or soon the galaxy map will be filled with nothing but "unexplored"'s.![]()
