I'm not quite sure what that means actually.

If your score is 20% and you improve that by 30% you score will be 26% which is
a rating increase of 59 Elo.

If the score improves 30% from 50% to 65% it's a 107 Elo.

If the score improves by 30% from 35% to 65% it's 240 Elo.

If the score improves by 30% from 60% to 90% it's 320 Elo.
