So what you're saying is that someone has a $30/hr winrate at 10/20 and a $30/hr winrate at 15/30 that their standard deviations will be different enough to account for the difference in level?

Yes!

Some other things to consider:

The formula relies on Win Rate & SD based on a snapshot of past performance. Since there is no guarantee that your performance relative to your average competition will stay constant in the future, you should monitor your performance and calculate your necessary bankroll to maintain your desired risk of ruin on an ongoing basis.

Also, you can significantly reduce your risk of ruin by adding a drop down (in level) point. Which may allow you to play comfortably at a higher level (with a higher risk of ruin at that level) with a smaller bankroll.
