Yes, I think this is it.
Version '1.2.3' - stable version at repositories of my system (Gentoo)
0.99667 = +7.3 sec desync
0.997 = +7.3
0.99834 = -3.3
0.99824 = -3.3

And with latest 'N-56704-g3e0c78b' version I have:
0.99667 = +4.0
0.997 = +2.4
0.99834 = -4.9
0.99824 = -4.5

So, seem like it is more accurate to decimals.Thanks for advise.
