Superchart problem

I am disappointed.
Blynk can only save one measurement per minute!

Such a fantastic tool as Blynk which con be used in a number of applications.
My application:
measuring rpm of a grammophone. This is not usable with report data per minute.
I need date per second.
Why is that not posible?
I am ready to pay if that is a solution.

Are you using Blynk Legacy or Blynk IoT?

Pete.
