Survival going up

It's because both the numerator and the denominator changes over time. Both of them go to zero. In your case there are only so many commits that reached 2.5 years old versus a lot more commits reached 1 year of age. So if the denominator goes down then the ratio goes up.
Hope this explanation makes sense
No, I can't wrap my head around this π³
Is the X axis project time or commit age?
X axis is commit age
here's a scenario. project has two commits, one from 2000, one from 2015. today is 2016. the first commit is still present in the code base, the second one was reverted in 2016.
first year: 100% because both commits were in the code base
second year: 50% because the second commit was removed
third year: 100% because now only the first commit counts (we don't know anything about the second commit, could be reverted in the future)
I see! (commits that age still present)/(commits that age)
, it makes sense. Thanks for explaining!
you got it :)
