Hi,
I tried it out few times, and I suppose I might be found the issue. Before I start explaining it I'd like to ask you wich was the starting text size value.
When you create an outline starting from a text you might have significant differences depending on the text size you're starting from. The outline will be created more accurately the bigger the starting text is, on the other hand, when the starting text is quite smaller, the outline will present few irregularities.
Those irregularities will lead to an inperfect text proportion and thus to the problem you experienced.
That said, try to create an outline starting from a bigger text size (eg. 72 pt)
Let me know if it solves your problem.
