That's a 15 average on 3x3, which I think most people would agree is mediocre.
Assuming a megaminx solve takes ~160 moves, you would need 5 TPS to get to 32 seconds. While 5 TPS really isn't that high if you compare it to the 8-10 TPS people are getting on 3×3×3, I'm also wondering if there's a much lower TPS cap on megaminx compared to the cubic puzzles. If, for example, for megaminx the TPS cap is like 6 TPS and you need 5 TPS to be world class, then that seems to be harder to achieve than 10 TPS on 333 with a 15+ TPS cap.
