 The accuracy is nearly perfect compared to software timers. The most important feature is they're ISR-based timers
 
 Therefore, their executions are not blocked by bad-behaving functions / tasks. This important feature is absolutely necessary for mission-critical tasks. 
 
-The `MultipleServos` example, which controls 6 servos independently, will demonstrate the nearly perfect accuracy.

 You'll see blynkTimer Software is blocked while system is connecting to WiFi / Internet / Blynk, as well as by blocking task in loop(), using delay() function as an example. The elapsed time then is very unaccurate
