As I previously said I am really concerned about diverging from what
arm32 has done here and the numbers don't seem any less real than the
ones we're using there (they were generated in an identical fashion).
Given the hardware availability for arm64 in general is limited and
likely to be even more so for big.LITTLE systems it seems like asking
for problems down the line to do something different.

Honestly I'm not sure there will ever be more real numbers that aren't
benchmarked at runtime.
