Double Manipulation?

[Thortok]

Here's an interesting synth fail, unrelated to craftsmanship issues. In this case it's a durability issue, and I wasn't watching closely but I assume if you use manipulation while still under the effects of the previous manipulation, you don't actually get the +10 to durability?
