Wadding Squares Getting Smaller?

Here's something I noticed when opening up a bulk pack of Estes C6-5 engines - 
The new box says there are 72 squares  of recovery wadding included, not the old count of 75. I know what you're thinking: "Come on, it's just three squares!"
In the engine bulk pack there were six small wadding packs as opposed to the old single large package. In the picture the new smaller size package is set over the old size wadding.
The old, larger wadding is made up of 4 1/2" squares. The new wadding is 4" square.

This won't  make that much difference in how effective the wadding is in use. It's just smaller -

At a club launch, Lonnie B. brought this up when we were talking about recovery wadding:

Toilet Paper Is Getting Smaller

Squares are shrinking and there's not as much on the roll

(NEWSER) – Does your toilet paper seem smaller to you these days? Well, you're not crazy: It is. As the Washington Post reports, toilet paper squares used to be 4.5 inches by 4.5 inches. Nowadays, they're up to a half-inch narrower, shorter—or both. (Apparently, it's enough of a difference to be noticeable to the naked eye: Last week, a reader wrote in to the Los Angeles Times complaining about a "26% reduction in surface area.") And, as Consumer Reports noted last year, the cardboard tubes are also increasing in diameter as the number of sheets per roll decreases. But the price is not falling: In 2012 and 2013, the unit price rose about 2% per year. (In 2013, the Wall Street Journal explained that the process of selling less paper for the same price is known as "desheeting.")

"A standard roll is much smaller than it used to be, so now they're selling double rolls. So, without being scientific, I think a double roll is pretty well equivalent to what a standard roll was perhaps a decade ago," a research analyst tells NPR. One not-as-obvious reason for the TP trend is that companies that make toilet paper also make products like paper towels and napkins. Though toilet paper is essential—Americans are estimated to use an average of 46 sheets per day, and that's probably not set to change any time soon—paper towel and napkin sales are falling. In particular, large companies, like offices and restaurants, are moving toward things like air dryers or, the analyst explains, rationing how many napkins they dole out to customers. But they'll never cut down on their TP orders in an attempt to ration that particular product, so orders will remain steady. (As for those hand dryers, you might not want to use them.)

Last year I was replacing a toilet paper holder in my guest bathroom. The holder center tube looked too long when the toilet paper roll was put on. This article explains a lot.
Companies that manufacture toilet paper certainly didn't publicize this.
Imagine that - "You get less for more money!"
