I should clarify that the 80% is meant to be 80% of what it was before the 10 pack (or any other variant) was there.

I estimate this because of the pattern of clicks we have seen as the scope of the 10 pack widens (it has been covering more places and categories over time, and we have identified new searches by the lowering of visitors for those terms in comparison to overall traffic and with the same organic positioning).
