As shown in Allanach et al. (Global fits of third family hypercharge models to neutral current B-anomalies and electroweak precision observables. arXiv:2103.12056), the Third Family Hypercharge (
) Model changes the Standard Model prediction for whilst simultaneously explaining anomalies in 
transitions via a heavy gauge boson which is spawned by a spontaneously broken gauged 
symmetry. The 2022 CDF II measurement of , which is far from the Standard Model prediction in the statistical sense, somewhat disfavours the model. Here, we generalise the gauge charge assignments to the anomaly-free combination 
and show that incorporating the 2022 CDF II measurement of selects a viable domain of integers s and t. For example, 
yields a p value of .08 in a two-parameter global fit to 277 electroweak and flavour changing b data, much improving a SM p value of
