Oh boy, what a standard when it comes to ballistics testing and charts. You have like a thousand people using that website per month man, that's not a lot of traffic, that really doesn't prove much of anything. There are a lot of charts that anyone can pull up on the ballistics of all sorts of cartridges. I would take a video with a chronograph over some chart that maybe a thousand people use per month. Since, at least with a video it requires more effort to fake then just typing out whatever you want to be the result. They even mention in their FAQ that it's not a full list of all of the different kinds of ammo you could be using.

They only use 3 different brands of 9mm luger. They also don't list what kind of chronograph they were using. That's not very much variability at all, especially considering there are 5 major manufacturers. There are over 50 brands offering factory loaded 9mm ammo in the U.S. market. They take 3 shots with each type of ammo. Lowest effort testing I've ever seen. Not conducive to producing trustworthy results at all.

They also only tested 1 gun with an 18 inch barrel.

Considering how much you need to do to make sure your Chrono readings are as accurate as possible.. most charts out there that are just for fun are likely not accurate in the slightest.
