The strategic benefit in the TE is that Chock/Bates would be expected to win both segments, especially if Lopareva/Brissaud are doing the FD, should FRA make the final. (They will have a Pairs deficit to make up.).
Whether they’d need/“need” to would depend on the points after the shorts.
After last season, I would have said that Carriera/Ponomarkenko were so solidly US 2, and Zngas/Kolesnik were barely in the conversation with four other teams, and could be expected to beat L/B and Davis/Smolkin, and/or possibly Lajoie/Lagha on neutral ice. (Were the Olympics not in Milan, a shot at Guignard/Fabbri.). This year, with their performances and material, no.
If Zingas/Kolesnik are US 2 this year, and were they to compete in the FD, the question would be the pressure, since their championship experience is two 4C’s vs. four 4C’s and two Worlds for C/P. Assuming C/B will skate the RD, and since the starting order of the RD will be reverse results of the RD, Z/K, if they are assigned, would likely be skating last in the first TE free. That won’t be the case at GPF, but skating late in the FD at Nationals would be a new experience, and hopefully it happens, and they get that experience.
A C/B FD would come close to guaranteeing at least two more points.
For the individual event, Z/K will earn 472 points minimum at GPF, which will surpass C/P’s total. Neither could catch any of the teams above them, since Gilles/Poirier should spread their lead at GPF, the rest of the European teams above them will get points at Euros, and C/B would be out of reach even without GPF. With the minimum, they should be 6th in WS before Euros, with Reed/Ambrulevicius passing them with 9th or higher, Smart/Dieck passing them with silver, and Davis/Smolkin or Turkkila/Versluis passing them with gold. So firmly in the penultimate starting group with 9th at worst. C/P will be 101 points more vulnerable, but they still should end up at worst, 10th. Without GPF or 4C’s points, and with unexpected results at Euros, Lajoie/Lagha could be bumped to a group (#3) which is after the ice cut, IIRC, which could give a boost to the US teams, if they are Z/K and C/P.
