Yeah 3 drums on each ship. My logic is if extra drums do make a difference, then it should be most noticeable with as many drums equipped as possible (excluding 4slots), compared to just one extra drum. We'd want to check if this factor is actually relevant before delving further into detail.

But in any case, I've temporalily put a halt to minimum drums to test this out too, mainly because I sent fuel to critical levels during my blitz to E5 and am desperate to try any method to maximise fuel for the final kill. Even with a small sample size of around 20, if more than 15 of them end up as great success then it would be enough to warrant further testing later..

Condolences on the melon...if it wasn't for KCV's damaged ship warning, I woudl've lost some ships by now too.
