New vesion has less variance for some reason.
I've ran a quick test - 5 runs, one after another, all equal, no net/FW/AV/extra running, same everything - the variance is not much now, only slight ->



Run1:
5.422 - Compute T
1.000 - Inverse T
6.422 - Total T

Run2:
5.391 - Compute T
0.984 - Inverse T
6.375 - Total T

Run3:
5.359 - Compute T
1.000 - Inverse T
6.359 - Total T

Run4:
5.406 - Compute T
1.000 - Inverse T
6.406 - Total T

Run5:
5.343 - Compute T
1.000 - Inverse T
6.343 - Total T

Averages:
5.3842s - Compute T
0.9968s - Inverse T
6.381s - Total T

Max Variance:
±0.079s - Compute T
±0.016s - Inverse T
±0.079s - Total T

Looks like you need to empty your MEM/Cache and run it for more accurate results - if I run it after using PC for a long time, Std starts to increase by much.
