Reread the temp measurements carefully. I threw out the "bottom of the radiator at the hose 200" as a mistake as it would be a hard target to hit without picking up something else.
If you throw that 1 measurement out, then you have a lowering of temp consistantly from the top of the radiator (236) through the middle (220) then to the middle bottom (150 probably low) into where the bottom hose connects to the bottom of the water pump (185).
If you go straight temp change from the top of the radiatior (236) to the bottom of the water pump (185) then you have a radiator doing it's job.
Now, if that "middle bottom 150" IS correct, then this might suggest blockages inside the radiator. Which would be really odd being it's a new radiator.
