recommended usually means not bony, and not bank-full.
guidebooks often state recommended levels. there are often runnable levels both below recommended minimum and above recommended maximum.
the trick is knowing your boat, your water reading skills, and the river in question to assess how much type II fun you are willing to take on, and how far into those margins you can go safely. Since you know the run already, and flows are within 20% of recommended, you should be fine.
but watch out for shap's line advice, he's a sandbagger!
