At BN-N sure, where the MERs are irrelevant.
I just went and looked at 2019-2021 results for Area 2 and 3 and within the first four hits I randomly clicked, found several 45+ scores at Training and above. One of the 2-star events I clicked had three competitors with a 40+ score after dressage, including a 46 after dressage that finished with no XC stops/refusals. These classes were not big, so having even one person score above a 40 is statistically significant.
Either Area 1’s riders aren’t as accurate or our judges are harder, but Area 1, while having fewer UL opportunities, had scores that skewed much higher. There were many 40+ scores, and several 45+ that finished with no XC refusals.
I don’t know if it is appropriate to post these rider names on COTH, but you can go to USEA and look up results pretty easily.
