I've replaced my annode bolt from mild steel to 316 stainless steel.
Is there any evidence that s/s will errode the annode faster?

Yes.
The evidence is that stainless is a better conductor and will make your anode erode faster.

Actually I think you will find that stainless steel has a higher resistance that ordinary carbon steel.
I doubt though of the differences in actual resistance of a few cms of 10mm stud will make any difference at all.
Anode fixing studs are available in either stainless steel or zinc plated mild steel.
The users choice I think.
The zinc plating will protect the studs when out of the water. The anode will protect them once immersed.
Id suggest that on a deep water mooring steel studs will be satisfactory but perhaps on a drying mooring the zinc plating may soon be lost and surface rusting will occur while out of the water. Maybe thats the time to consider stainless studs despite the risk of a little more galvanic activity while afloat.
