Log your toilet paper measurements

Are toilet paper rolls getting smaller? The prepper blog The Prepared measured a “pre-panic” roll side-by-side with a “post-panic” roll, both of the Sam’s Club brand. They indeed found that the newest roll has decreased in diameter by three-quarters of an inch.
Both appear to be unbroken rolls.
It’s possible that they have peeled off a few layers to doctor the evidence because they’re in bed with Big Bidet. But I don’t want to believe it.
I’ve long since blown through the February toilet paper supply, so I have no independent evidence to prove this.
