Yeah! I got the wrong end of the stick from something I saw on a clip from BBC News on Twitter but then couldn't find it again where they mentioned the 70%, but upon finding this tweet from John Roberts, the line is closer to a 40% divergence on current numbers (although this could still change as incomplete).

They did a breakdown by area (I can’t find it now) one trust was as high as 70 percent, Birmingham from memory.
