User blog comment:OceanSushi/A Mini Research on the Optimal Maruyu Batch Size/@comment-26154973-20160224100353/@comment-27143098-20160226005547

So from what I gather the conclusion(s) are:

1. The mean luck output per Maruyu Kai tends towards 1.6 for every batch size

2. Standard deviation of luck output will be wider for batch size <5

3. Using batch size of 2 is a viable option if you lack ship slots to store more Maruyu due to the high chance of higher total luck output

Feel free to correct me if I misunderstood something, thanks!
