It was a fun and interesting exercise. All the years were good, but 7 and 8yr were definitely a step up, with the 8yr easily being the best.
That was to be expected. It was more about having a clear example of the year to year differences. The 5 and 6yr were about 10 proof points lower than the the 7 and 8 though, and that was very obvious in the richness and color jump between 6 and 7.
