As David alludes in a separate reply, you can initially get away with very low clearance angles. As I pointed out in yet another reply low-angle shaves are invariably operating with a couple degrees of clearance, and as you found you can go lower still.

The catch is that eventually a wear bevel will form and further reduce effective clearance. How quickly that happens depends on both the wood and the steel, specifically the latter's balance of abrasion resistance vs other attributes, which determines whether a wear bevel is likely to become objectionable before other failures modes like chipping or outright dulling. It also depends on how willing you are to press a recalcitrant plane into the cut.

So as usual, my opinion is that there is no single right answer. It depends.
