  We revisit the impact of top partial compositeness on electroweak precision
observables in the misaligned vacuum basis. We identify a new source for $S$ in
the singlet mixing case, and for $S$-$T$ in the bi-doublet mixing, stemming
from misalignment in the gauge couplings of the top partners. Hence, a positive
shift in $T$ can be obtained in both cases, as preferred by the recent CDF
measurement of the $W$ mass. These results, obtained for the minimal
fundamental coset SU(4)/Sp(4), apply to any composite Higgs model with top
partial compositeness.
