I will try to develop a more complete explanation of the two major tests and how they are to be applied. For now, it is important to realize that explanatory power is about explaining the data we currently have and predictive success is about making predictions about the data we will be discovering. Einstein's theory was successful because it made predictions that were later confirmed by observation. If a prediction is not related to the future, then it is not a prediction.
Well, if you wish to change the vocabulary of the scientific method, then I would say that "prediction", in your sense, is also not necessarily a good test of a theory, and at best is only a subset of the ways in which a theory can be justified.
I instead propose the following comprehensive test: the comparison of the logical consequences of a theory to the data presently available to us.
I would also wonder why it is necessary for you to alter and/or obfuscate the scientific method, but I think that will become clear when you start actually discussing Ross's stuff. Really, if you can't play the game by the same rules as everyone else, this suggests that the cards in your hand aren't that good.
