Alright, I'm going to apologize in advance for anything I didn't get right in my last post. I had to make a couple assumptions about your attack, due to a small lack of detail.
The primary assumption I ran with was that the attack was a light one that didn't have a lot of power behind it (since your saber was held in front of your chest and wouldn't have had much space to build up power, and also because it was one-handed), and that it was a swing from your left to right (or my right to left) that was about chest height (my chest height).
The other option was that it was a slash from your right to left, but that would leave your left-hand saber in a poor position to defend once the strike was finished, since your right saber would then be crossing in front of it. So I went with the first option.
I also assumed your stance remained mostly even and head-on, since you never specified otherwise.
