I'm sure your average didn't stay the same, only may the move be invisibly small.
Is your TL average saturated (>500 TL scores available) or not?
If so, a prediction is difficult as we don't know which score was eliminated, determing the move.
If not, the number of scores available would be relevant - any idea?
As a wild guess, with a mid number of 250, the difference of 1.13 divided by 250 would be around 0.004, with a good chance to stay invisible.
