Here are my results from testing this patch. It appears as though the
stepping "works" for the first step and not again. However, the first
step shows a approx. 20% increase, I was expecting something closer to
12.5%.

If you need any more information or have any other patches let me know.

PS: Your patch is against 1.24 and a 1.25 was committed the other day.
1.25 was just an asthetic patch it seemed though.
