General aviation pilot reported a critical ground conflict at a non-towered airport with an aircraft that did not enter the traffic pattern correctly and then overflew the reporter's aircraft during go-around.

Narrative

I was entering (45 degree) left downwind for runway XX at ZZZ in a RV10 and heard a SR22 call a 7 mi final for XX. I announced downwind and looked for him. He announced a 5 mi final. I announced my turn to base and stated that I did not see him. He replied that he saw me; to which I replied 'Good; I feel better'. I assumed (incorrectly) that; given the traffic in the pattern; he would break off final and enter the pattern. I announced short final and landed and exited the runway as quickly as practical. As I exited; he overflew fairly low in a go-around. As I taxied to the hanger another aircraft announced in the pattern and the SR22 pilot asked if he could get in as 'someone else had just cut him off.' I assume that he was referring to me. This makes me consider the possibility that he thought that he had the right of way (over traffic in the pattern). On a flight from the North I also hope for a straight in to XX; but enter the pattern if there is other traffic and certainly know that I do not have the right of way in such a scenario. I report this only to add to the statistics and highlight that apparently some pilots (despite bulletins on the subject) are unaware that they should enter the pattern.
