Let's assume that the ring is for emergency use in a situation where you have concluded the engine is going to remain silent and you want to find an airport ASAP. The airport you select must be inside the ring, right?
You need to determine to your own comfort level what the glide ratio of your airplane is with the prop either windmilling or stopped. I suggest you use whichever is worse, probably the windmilling one. Of course, you also need to determine experimentally the IAS for that situation. Examples can be found in Cessna POH's but of course your RV-12 will have different numbers.
Since I don't have a Garmin Pilot, this is an educated guess. I hope it helps.
