The level scale for the penalty is still the same, with severe penalties starting at ~5 level difference, mild penalty at 4 levels and no penalty on 3 levels or less.
What you should find adjusted now is the malus, the severity of the reduction of willingness.
The adjustments seem to have taken its first effects from what I can see, the frontlines have progressed quite a bit since the changes where made. Before progress was notably stagnant.
I'm a bit hesitant to recommend making the penalties even smaller or the level range greater. Right now the speed of how fast players are advancing seems fair.
