We're approaching the end of the period, that's why there is no more such exponential growth, there is only a day and a half left, for it to change the current 8% to 10% you would need the last of it to be even higher to compensate for the lower average over the previous 12 days.
That aside, the current pace (24hours) is actually quite high, 174 blocks, around 22% higher than the average, it might push the adjustment to over 9 if this continuous and it's not just randomness.

From the 13th we had 5 days with block time under and ~9 mins, there is definitely more gear coming online.
We're penalty going to beat the May ATH and let's see, another 6% is enough for over 200Exa on average, another milestone and record, not one that I'm too thrilled about.
