Nay lad, you only mentioned credit cards. I mentioned the ISO standard that covers such cards and you now claim you meant something else. Both posts are there, read what you actually said.
You wish to add to what you said, do so. But I'll tell you again to do your homework before replying.
I said this:
And, Mister roubaixtuesday

The Big Drawback of that Safety Plus: 20 grammes, or make it 40, 80, ... 1 second more per mile, due to the presence of about half an apple in your pocket.
Fine to win a fitness race by cheating, but to commute, shop, well, 20 grammes is the weight of a credit card. Some people have 10 of those in their wallet. At the cashier they then spent 5 minutes search and try to, alike the HollowTech2 chainline story, stuff together the ticket price.
The next customer then pays cash and passes in 20 grammes err I mean seconds.
Btw, how many credit cards do you have?![]()
No, I talked about a 20 g credit card:

You talk about "usual plastic cards".
I compared the Hollow Technology of the race cheating of the Weight Religion to a 20 grammes credit card.
Then you came in, talking about 5 grammes plastic credit cards, ISO standard and homework.
A 20 grammes credit card is a 20 grammes credit card.
Why do you talk about a 5 grammes one?
Do you have any point at all with it, other than attempting to squander the discussion?
To remind you:
The point of the discussion was the weight "penalty" of a 50% thicker (to the inside) shaft wall, compared to the safety "reward" of a 29% better resistence to torsion breaking.
That penalty, as calculated (see link to a sites dedicated calculator) in the last, was 20 grammes, being a credit card weight. One can instead of HollowTech2 leave his creditcard home to win the race with the same effort, and bonus, 29% less prone to snapping underway.
