you should also consider high instantanous loading like turns, bumps, start/stop loading, etc... these instantaneousloads can be 5 to ten times rider/bike weights...
and the wet weather testing should be more similar to actual conditions... simply pouring a liquid mixture onto the bearing every now and then is not a good experiment.
then, there's the fact that MOST bikes have simple mechanical seals... no rubber lips contacting race/shell, etc.
and "automotive grease"... which one? there are HUNDREDS of different grades/formulations. I keep 5 types in my garage... each is quite different from the others.
