As previously stated, with corks, d-spins, misties, rodeo's and flatspins, the inversion is counted as part of the overall rotation. For some reason, which really causes me to dislike the underflip label, it breaks down and no longer applies with underflips and overflips, as you simply disregaurd the rotation. Confusing, I know, which is why I would love to phase out the terms, or at least get them to agree with the rest of the system.
