Advertised as 22 miles but I'm getting 10 miles on a charge Is that normal?

Ein Reddit-Post mit dem Titel "Advertised as 22 miles but I'm getting 10 miles on a charge Is that normal?". I am getting 10 miles on a charge on flat Florida paved street in a community ... I am 180 lbs
Is that ok?
I got this
MAXSHOT Electric Scooter Adults & Big Kids, Top Speed 9/16/19/22MPH, 10/12/16/21/50Miles Range, 6.5"/8.5"/14" Tires Folding Commuter Escooter with Dual Suspension for Commuting, APP Control
https://www.amazon.com/gp/aw/d/B0FNRGML9X
The DualShock one
\>V1PRO-19MPH-Dual Suspension
Or maybe I'm not reading the advertisement correctly? What are the correct specifications for?
It from my understanding 20 miles range on the charge?
But I guess that's if your way 50 lb...
I am 180 lbs
PS What app can I use to connect to it on Android?
And what do you think would be a way to connect? When I turn it on the application should find it?
On the pictures on Amazon it shows that it has a companion app
I'd love to see the total miles that I have written...
Thank you
