I'm responding to this comment on your wall, because I don't want that question to be derailed any more with discussion about why it is flagged. (In general, please don't leave comments about flags on posts unless it's absolutely necessary. It makes a mess and becomes very tiring.)
The reason the question will stay up are as follows:
* I already made my 'final decision' in the first comment I wrote, and the reasoning stands. The newer question specifically requests the chance of Pokerus spreading *between Pokemon in the party after a battle*. (See below for why the answer you wrote does not solve this.) The older question contains no such distinction, and that is why the answers on the old question do not solve the newer question.
* The question isn't opinionated (or 'low class'). Probability isn't a matter of opinion.
* Maybe you can't solve the question by searching it up on Bulbapedia, but that certainly doesn't mean the answer can't be found at all. The probability could be found through datamining or extensive testing, in the same way other probabilities (e.g. Shiny chance) have been found.
On Bulbapedia, the following is written: "If any of the player's Pokémon are infected, the Pokérus may spread among Pokémon in the player's party after any battle."
The question is asking for the probability that this will happen. It is *not* the same as the 3/65536 chance that is mentioned beforehand.
Please don't leave more comments on that question. If you still have problems with it, then send them to me instead so the thread isn't derailed any more.
