The point gain from sanma tonpuu is miniscule, and given that even the best players in the world struggle for stable Saint 1 performance in Jade sanma, it might be better to stick to hanchans and hope to luckshit your way out on a good streak, especially for you as Expert 2 is still positive on average.
That's my thinking, unless there's data out there saying sanma tonpuu takes less than half as long as hanchan games on average, making the former more efficient to grind.
