Mmmmm
I used to fly a light single, where the stall speeds were calculated without reference to weight, but the approach speed had suggested factors to reduce it at lighter weights.
It was possible to fly the approach less than 1.3vs and yet comply with the POH.
It could have looked tight (per your comment BOAC, which I understand), but the reality was that it was perfectly okay.
I don't have the POH to hand, so I can't honestly say if it was 1.2vs or 1.1vs, but you probably get my point.
