Speed ratings were higher for FL than NXN, just saying
According to Tullyrunners, yes.
According to Watchout, they are very even.
This is where speed ratings are not perfect. Two different races with two different individuals that use different points for their speed ratings.
Usually the two raters are not too far apart, but for the top runners from each race here is what they reported:
As you can see, Footlocker they agree upon. However, NXN there is quite the discrepancy. Watchout has the ratings 3.4 higher per runner. Correct me if I'm wrong, but each point is 3 seconds, so thats about 10 seconds difference in ratings for NXN.
I will use Dressel and Anderson as my comparison since they both had similar races at their respective national meet and have raced many times throughout the season.
Dressel and Anderson have been racing very near each other with Anderson slowly closing the gap until the state meet where Anderson pulled away and won with a 200 speed rating. I think if Dressel and Wilmot didn't give up during their races at state that they would have been very close to Hardy and Anderson. But they both were jogging the final stretch.
Assuming that Anderson raced near his state meet level (which he raced very similar) then his speed rating would be near his state meet rating. Also, Anderson has finished a few seconds behind Dressel many times throughout the season, so that would account for 1-2 speed rating difference. They both had great races at their national meet, so their speed rating should be within 1-2 of each other.
