What if the % of a "virgin" CT is a rounded off number aswell? e.g. instead of 50%, anywhere in the range of 49,50% - 50,49%?

What if the 2% skill increase is not exactly 2%, but say: 1,92%?

Another thing I noticed which might be of help, I extracted a virgin 50% ct with no skills and it turned to 45% in private storage. Then I put it back in the factory and it changed to 44%...
