This is the tenth year that I have been tracking these figures. Last year's winner was fifth out of six; the previous year's was third out of five. The top ranked novel on this basis won the Best Novel Nebulas for 2017, 2016, 2015 and 2014. The 2013 winner (Ancillary Justice) was fourth of eight. The 2012 winner was second of six. So was the 2011 winner. So in the last nine years, the top-ranked novel on this ranking has won almost half the time, and one of the top two has won two-thirds of the time.
Striking that Mexican Gothic has more owners on LT than all the others combined, but the lowest reader ratings on both systems. Of course with best-selling books, it's often more likely that readers who didn't like them will register an opinion.
Skipping the Novella category because not all of them were separately published.

Last year the fifth out of six finalists won (as with Best Novel). The previous year, the top-ranked finalist in this category won. I failed to do the calculation for the 2017 award; for the 2016 award, the winner was fifth out of seven on this ranking.
