Surely the “dragged points” are only the ones gained against the other clubs who have progressed to the next stage? Done to stop clubs having to play against each other again and again and again etc.
Dragging the points totals from the first mini league is madness. It’d allow a team who won Group X who may actually be so bad that they’d finish bottom of group Z to enter phase two with more points than the winners of group Z!
If it actually is the total number of points being dragged then quite simply the Spanish football authorities aren’t fit for purpose.
