Trending @Capgemini; Im a5 now got exceptional rating with promotion. How much will i get hike. Any idea on this???

I was A5 last year and had got exceptional rating as well as a promotion to B1. I had got around 30% hike

I got 22% hike while I was A5 after the year end and promotional increment altogether. I got the promotion letter at the end of march there the new ctc was reflected. I got the rating 1.
