> What happens to the time if you replace that function with:
This helps about 5% but it does not get the score back up.

3.4.0's score for this machine is about 900.
4.1.0's score is 720.
4.1.0+scource modification is about 780.

so it helps but there is something else which needs to be improved still.

I don't think this is a RA issue now after looking into the source.
