Well, yes, but what does 2% failure rate per year even mean when it’s presented independent of a number of uses per year? I mean, without knowing what number of average uses were used to calculate “2% failure rate per year”, it seems like somewhat of a misleading statement, as I’m reasonably certain (let’s say at least 90%) that it’s not intended to reflect that condoms become more protective the more chances you have to use them.
I feel like I’m missing something basic here that would let me see why it’s a useful piece of information on its own.

This is a good observation. You can look up what the average number of uses per year is. If I remember right, I’ve seen some condom efficacy studies include that information.

You’re not missing anything basic, you’re correctly perceiving ambiguity where ambiguity does exist. Even when information is really important, I’ve found that it’s often been omitted simply because products are marketed to the average person, not to nerdy people like me, and most people don’t want to think as much as I do. For this reason, I’ve found it’s very important to be careful not to assume that the world is doing sensible things or giving me all the information. They’re not just leaving information out, they’re also not being held accountable by a world full of people who think as much as I do. Therefore, they can get away with slapping various nonsense marketing claims and out-of-context data on their boxes without people questioning them.
Thanks for taking a moment to let me know that my comment is appreciated and that this information makes a difference for you. I find that, like Luke says in The Power of Reinforcement, knowing that a behavior of mine has made a difference and is wanted “increases the probability that the behavior will occur again”.
I think LessWrong could really use more positive reinforcement, so I hereby positively reinforce you for showing the humility to positively reinforce.
I agree it’s misleading. That’s why I’d prefer a metric like this, where the precise definitions you use don’t matter if they are the same in both the numerator and the denominator as constant factors would cancel out.

Yeah, this is good advice in general, and it’s definitely what I was doing wrong this time.

You’re welcome.
