Your cruising a/f might be a tad rich but you won't know until you try. I would suggest low to mid 14's for cruise.
Your mid 12's sound good for WOT and this should be your richest a/f reading. Your 11 readings for enrichment are too rich. I would suggest making your part throttle enrichment a/f numbers be in between your mid 12's for WOT and 14's for cruise. The enrichment numbers may vary pending on the seat of the pants feel of the driver.
My cruise numbers from 30-70 are currently at 13.6 to 14.6. My enrichment for light throttle is 13.8 to 14.2 and my WOT is 12.8 to 13.0.
Each motor combo will be different, but over the last year of driving with an a/f sensor, the above numbers are what my current combo and my butt-ometer feel are good driving numbers for my car. Hope this helps.
