2HKO Probability Calculator http://tangerine.colinjf.com/probcalc.py Web Interface version, which should be accurate. Fill it in, and give it a whirl. Description: The Calculator aims to calculate the probability of a 2HKO with regards to the Random Number component used in the Damage Formula. You can put in different moves, and different "effects", to see the actual 2HKO probability rather than just guesstimating. Implementation: Calculates the Damage of the 2 moves, applies the Random Number component, applies the rest of the modules, and then sums up the conditional probabilities. It is done on Python and CGI. How to Use: Take note of the variables it asks for. If you don't know what they do, then take note of the Damage Formula. Plug in Numbers, and give it a whirl.
