You could replace a 5 speed 14-16-18-20-22 with a six speed 13-15-17-19-21-24 and still maintain half-step progression using the same chainrings.

I didn't realize that was what the half step indicated, it guess I'll leave mine alone if changing the range will cause me to lose the supposed benefits of the half-step. I will check the bike and see but I believe my spacing is 14-16-18-20-23-26.
I just checked and the spacing is 14-16-18-21-24-27.
