So, imagine it in this situation. You have a...max IV shuckle with max Special Defense EVs. You are using a venusaur with weather ball with max special attack IVs. . We are assuming that you got the max roll. The weather is the rain. Both Pokemon are level 100. The shuckle also has max HP ivs and a calm nature. Venusaur is running max Special Attack IVs and a Modest nature.

Based off of this, we will have:

(((((2*100)/5)+2)*100*(614/328))/50)+2)*(1.5 (weather) \* 2 (super effective)

From this, we get: (20*100*(approximately) 2.0374) * 3

The final answer is 12224.4

Don't ask me how this is used in other calcs XD
