Trending @Accenture; How much hike should i expect for promotion from CL-9 to CL-8 at Accenture?

For level 10 what is the hike% should one expect?

20-25% mostly 20 percent

Are poll results true ?

If you are the top most performer and the management has faith that you will not run away and stay back. Then 25 max. That's the max. And in rare scenarios they would exceed that
