sorry not sorry for double post
https://cantsay.github.io/resources/ko-chance-calculator/ (if it doesn't work try http)
Added a web implementation of DaWoblefet's new KO Chance Calculator! You can read up on how to use it here, but is has some pretty groovy application! It's capable of accurately working out the odds of your pokemon living up to 5 attacks (more than 5 starts to crash browsers, use the Java Applet if you need to calc more than 5) - this has utility in doubles obviously, but also in singles for accurately calcing multi-hit moves (as described in the link provided) and also successive attacks with stat drops, such as a Draco Meteor followed up by a -2 Draco Meteor. Enjoy!
