great review by @Oliver and @Jakob! You could almost have handed it in as a master of rum thesis 
It confirms my subjective impression that last year was a bit ‚quantity over quality‘ with the considerably lower number of 90+ ratings in the top 10.
On the discrepancy of bottles bought / opened bottles vis-a-vis bottle splits (samples), I can only tell for myself, but I have to admit that I do not change this status of bottles/samples, and I assume quite a number of other members do act the same lazy way…
looking forward to reading part 2!
