Following the blame rabbit hole I found this:

254753dc321e ("sched: make the multiplication table more accurate")
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=254753dc321ea2b753ca9bc58ac329557a20efac

which sounds like it would explain some small deltas if compared to a 
formula that is set in stone.

Hope that helps.
