Let's fill in those gaps in the information: Shortly after the drum-expeditions were introduced, an anonymous poster wanted to better know how the number of drums and sparkles effect the GS-chance and asked for help in gathering the data. So all the sources come form anonymous posters and were gathered by that one anonymous poster. I personally contributed around 40 samples for that.

It might be possible, but not very likely, that things changed since back then.

I don't know about the distribution of the drums on the ships. In my personal tests, I had more than 1 ship with drums as well as at least 1 ship with more than 1 drum.

During that time, I experienced a day were the GS-chance was above 80% as well as a day were the GS-chance was below 30%. Probability just works like this and you really need a good number of samples to get any sort of useable results. I personally also had the feeling that the GS-chance was really low until I started logging for the test.
