>always is correct

Now you are just being disingenuous. You and I both know that this wasn't your first use of the word "always," nor was it the one I was referring to.

>my very first answer could have specified "always in epidemiology studies", but it was evident from context;

Really? Your very first answer include the following example:

>It's like if you're trying to check if two dice are loaded, but there's one die you can roll every few seconds and another you can roll only once every hour

The reality is that, unless you are suggesting that rolling dice is an epidemiology study, then the context clearly wasn't limiting your claim to epidemiology studies. At the very least, the context was applying your statement to dice rolls as well.

EDIT: Funny that you don't even attempt to address my claim (e.g., at the very least, the context of your example was meant to apply to epidemiology studies and dice rolls). Instead, you just make a reply that doesn't attempt to address this point and then block me.
