This is an interesting result but I have trouble taking stock in it. QCD disagrees with proton mass by ~2%, and is insufficient to explain why He3 is a stable.

I realize the 3body, and 9body (!!) problem are complex but when a theory disagrees with nature that fundamentally it casts doubt in my mind.
