is that a better explanation?

Yes, and I actually grasped that. But, unless you *really* dropped the ball in your mixing of fuels, that scenario is next to impossible. Looking at it that way, you could have all sorts of scenarios play out for the negative. What if the fuel you received from OK was watered down? What if it had degraded? What about summer fuel vs. winter fuel? (drastic differences in 93 here) All of these things are really sort of moot. If you really wanted to tune for 93, the mixing is easiest route. And I was just throwing it out there to help.
Edit - saw your addition. It's cool. Whatever you guys feel is best for your company. Truly was just trying to help you out. If it is really not an option for you guys, no worries. If you want to know more about it, here is a good fuel company created chart on mixing for different octanes.
