I agree, the inherent differences with (light) corporate biz jets and the airline world make this discussion meaningless. The two are always going to disagree.
In a light twin (seneca) I'd stop if I was still on the runway (there is no V1), plus at 80kts or there abouts chances are you'd stop on the runway or have a very low speed over-run. But in an airliner, above V1, I'm going, unless a catastrophic failure prevents me getting airborne.
