If you had a 4×1 that went 52.9 at a meet with one lineup of 4 girls, then did a TT in a practice with the same girls but in different order that did 53.6 would you make that change? Basically I am putting my best 2 runners on the curves with the 3rd leg being about 115m and putting the slowest girl as anchor. They only ran against themselves.
One girl did about 10-12 vaults today in practice beforehand the others only did relay handoffs before the TT for old order. I only told them today about the TT.
