   Yes the final answer would be 1 because we are rounding up.
   
   I went for underestimate because it is better for IndexAndDocValues query so there is my bias. 
   
   Maybe is a better heuristic to divide the points per document by 2 so it we hit half of the points then we consider one doc. Still in your example the result would be 1. 
   
   Or we should disable indexOrDocValues all together for multi-value fields?
