It's clearly at least a low end Cat.5, but I won't go too far beyond that.
I'd also like to present Cyclone Olaf of 2005. It's basically a SPAC version of Dianmu with the most perfect structure ever observed in southern hemisphere besides Monica. The cyclone undergone a phase of rapid intensification under extreme favorable conditions consisting of 31°C SSTs with low shear and strong diffluence aloft. MODIS imagery indicate the eye is well over 20°C and is surrounded by insanely cold CDO. A barometric pressure of 931mb was recorded on an island of American Samoa when Olaf passed more than 25km to its east after significantly weakened. It's possible the central pressure went as low as 900mb at the time and we can only imagine how low it could have been near peak intensity.
Since I can quickly implement the Schloemer Equation via Python, I used it with Olaf '05, and the results are pretty eye opening. Using a 18.52 km (10 nm) RMW that I've estimated using microwave imagery (below) and spitballing a very low 1000 mb outermost closed isobar (just an educated guess since I don't have access to reanalysis data with the government shutdown) along with the measured 931 mb pressure estimated at 25 km from the center of Olaf, I end up getting Tip type pressure estimates. Even if Olaf passed a little closer and the RMW just touched the observation side, that's still good for an 890 mb pressure estimate. A developing outer eyewall may have affected the pressure gradient a little, but I don't think that would have resulted in a pressure above 900 mb.
