Just make sure of your measuring device, the last 2 generations of range finders I’ve purchased compensate for angle and show the ballistic range rather than actual measurement.
Shoot the same distance in the fall or winter when the temperatures are likely lower. That will make a big difference on a zeroed rifle vs summertime temperatures.
Strelok can use your phones accelerometer to give you the slope also.Just make sure of your measuring device, the last 2 generations of range finders I’ve purchased compensate for angle and show the ballistic range rather than actual measurement.
SIG KILO 2200MR.... is that new enough?

I'm not good enough at the math, but the angle will mean the bullet is actually traveling slightly less than 100 yards. Someone smarter than me could calculate the exact difference. But it won't be enough to matter. Just guessing, but if you set your target at around 105 yards that would compensate for the difference.
And it doesn't matter if you're shooting uphill, or downhill. The actual horizontal distance the bullet travels is somewhat less due to the angle. This is only an issue when shooting at much longer distances, and with much steeper angles. It's actually more of a problem for archery hunters shooting from an elevated stand. If you're 30' up a tree and shooting at a deer 30' away the deer is actually only about 20' from the base of the tree. With the arched trajectory of an arrow that is significant.
This is the answerThe cosine is the trig function that would give you the answer to your question. If it is 100 yds measured along the ground surface, a 12.5* slope translates to 97.6 horizontal yds.
For only slightly over 2 yards I wouldn't bother with any compensation unless it was a benchrest match for money.
