Earlier quoted context omitted.
I'd need to know the full distribution of MRP% for that. All I'm saying is that merit lines were not such that it was possible for the mean raise to be 1%. It requires way less data to see this.
So you don’t have the data but you know that the mean raise for SI is not 1%. Basically “Trust me bro!”
"Mean raise for SI" is also not what the original post said. It just said "raises for most employees was between 0% and 1%". We can't exclude the higher performers.
Zero people on my team had raises below 1% (one was close). Nearly my entire team, including me, received SI for 2022. The merit lines make it clear what %MRP you'd need to be at to get a 1% raise and it is well above the norm.
