So, how that STRAKS test went?) I'm running nodes for new coins and then switch to WTM when they appear there, generally WTM avg diff is 0.5-5% higher than the real one.
The only exception is STRAKS where it's always 20-25%. Considering 5-10% or even more can be wasted on some random things during mining, it can be closer to reality, but still it's not right.
I prefer correct values and then you can apply -10% if you want it to be more realistic and not theoretical.
