We usually use BFL v1, and we can choose v1 max and v1 min.
There is no right answer to your question. It's really that simple. Your calculated V1 is invalid because of an external factor. Boeing provide some advice in their FCTM but it all comes back to crew judgement. BTW, we all live with QAR. Just use care and sound judgement and you'll be fine.
