Isn't a contributing factor the stock cat/exhaust design?

I only mention this as it seems like fast intentions recesses the 02 slightly to avoid this problem as mentioned in their high flow res cats:

"J-Bend style O2 sensor anti fouler to keep that pesky CEL (Check Engine Light) off. Note: In rare instances, model year 2013 and above, may trip a CEL (Check Engine Light)"

370Z Resonated High Flow Cats, Fast Intentions

.....

Or it could just be it's a '09 / higher miles and they're toasted after racing those notoriously fast Subaru Outbacks to the nearest starbucks?
