I've not really done the sums (so do could correct me if I'm wrong), but given the overlapping salary scales, the additional 1-2 months' PB could quite easily offset the 'lost income' from a direction promotion to SEO1, unless perhaps you are already at the ceiling of your GEO scale, or your performance would have also scored you A/B as a SEO1. I suspect for the majority of young KPs, the hypothetical financial loss isn't actually that big.
