No, thats the result after he got all percents up by 10%. He told me that he got it on the phone, and hes jealous of my Twin Brand and Delsaber Sheild. So he trying to bribe me by getting that Red Saber so good.
EIT: All percents except Machine though, That must only have gone up by 5%

Both your original and editted posts are incorrect.

The lowest percent you can find a weapon with is 0%. Any areas with 0% will never tekk to anything different.

If the percent is 5 or above, then it will always tekk to 10% less, 5% less, the same, 5% more or 10% more. When a weapon is tekked up 10% for example, all areas are tekked up. There is never a difference in areas tekking more or less than other areas.

Just in case you still don't understand, here is an example:

You find a special weapon with the percents: 5, 0, 50, 10.

Now, this weapon's percentages can have any of the following values when tekked:

1) -10% (-5, 0, 40, 0)
2) -5% (0, 0, 45, 5)
3) 0% (5, 0, 50, 10)
4) +5% (10, 0, 55, 15)
5) +10% (15, 0, 60, 20)

So obviously, you should always aim for number 5. Sometimes it can take a lot of tekking to get the best result, so it is advised that you save the game prior to beginning your tekking, thus allowing you to reload if it takes hundreds of attempts.
