It's quite simple - you do what you briefed to do.
If your brief states "Up to nn kts we will stop for any malfunction - above nn kts up to V1 we will stop only for engine failure, fire, smoke indication, blocked runway <flood, famine> ...." then you stop. Woe betide the captain who goes against briefing without a good reason.
IMHO an ASI disagreement is a very good reason to stop, since you are well below V1.
I can't think of a good reason to continue the takeoff.
