Looking at the Footlocker and NXN girls results, I noticed a few competitors who did the double. Going by how far behind the winners they were, one can roughly estimate how the two races would have gone as one.
Taylor Ewert - NXN: -29 Footlocker: -20
Emily Covert - NXN: -33 Footlocker: -29
Ericka VanderLende - NXN: -50 Footlocker: -43
Allison Wilson - NXN: -56 Footlocker: -50
Grace Ping - NXN: -86 Footlocker: -109
(I assume her Footlocker was a bomb)
Katelynne Hart - NXN: -53 Footlocker: -1
(I assume her NXN was a bomb)
If the two races were one actual championship I would guess the results would be something like this:
1) Katelyn Tuohy
2) Sydney Masciarelli -7
3) Katelynne Hart -8
4) Kelsey Chmiel -17
5) Abby VanderKooi -21
6) Taylor Ewert -28
7) Emily Covert -34
A lot closer to Tuohy than I would have expected, tbh!
