RBY OU Rating special attacks

I decided I'd write down all the relevant special attacks and their strengths. The most important ones are bolded. Note that some attacks are omitted due to sharing Special and Base Power with another attack (e.g. Birds' and Eeveelutions' STAB moves); I have not omitted the one case I found of two attacks having identical power due to Base Power and Special differences cancelling out exactly.

There are also some NHKO cutoffs for the four most relevant neutral (or neutral-ish) targets.
