what it takes to move upHolding the other metric constant, these are the reductions needed in qubits or Toffoli to close each gap. Real mixes of both will get there faster.
Pass fortunexbt +1,518,813 score to cut
If q stays at 1,542 −985 T avg Toffoli reduction
If T stays at 1,682,159 −1 q peak qubit reduction
