I wonder what that 25 number actually means. It’s 25 across multiple slot types so I’m guessing it’s less a measured value and more a quality control number based on their most fragile product.
Probably something like a sample is cycled 25 times and if less than X% still test as being in spec they know something is wrong with the current batch, but again that’s mostly a guess and the actual durability experienced by the end user would vary significantly depending on what the acceptable failure rate is.
I have a really distinct memory of finding a bunch of these in a friend’s house when I was a kid and every one was empty. After watching the TC video I think it’s more likely I just wasn’t pressing hard enough and had no way to know that. Anyway, I can see why they stopped making them.
