I'm just explaining that you can't translate that to an Elo number without
knowing how many games there were in total.

If you play a total of 10 games and score 7 without book and 10 with book, your
score has improved from 70% to 100%(!!) which is a huge improvement (800 Elo).

If you improved from 7% to 10% its a much smaller improvement (70 Elo).
