Making a joystick control for two servos to hold position

I make it to work as i want.Here is my code:

#include <Servo.h>

//#define mainArm 0
//#define jib 1
//#define bucket 2
//#define slew 3

Servo servo[4];                                  
int angle[4] = {100, 100, 100, 1472};             

byte potPin[4] = {A0, A1, A2, A3};
byte servoPin[4] = {12, 11, 10, 9};               
                                                   
                                                  
void setup() {

  Serial.begin(9600);
  Serial.println("Starting DiggerCode.ino");

  for (byte n = 0; n < 4; n++) {                  
    servo[n].attach(servoPin[n]);
    servo[n].writeMicroseconds(angle[n]);
  }
}

void loop() {
  readPotentiometers();
  moveServos();
  delay(10);
}

void readPotentiometers() {
  int potVal;
  int button = 1;
  for (byte n = 0; n < 4; n++) {
    potVal = analogRead(potPin[n]);
    potVal = map(potVal, 0, 1023, 544, 2400);
    
    if ( button == 1){
      
      if (potVal > 1572) {
        angle[n] += 10;
        if (angle[n] > 2399) {
          angle[n] = 2400;
        }
      }
   
      if (potVal < 1372) {
        angle[n] -= 10;
        if (angle[n] < 545) {
          angle[n] = 544;
        }
      }
      if (potVal < 1372 && angle[n] > 1572){    //kick off code
        angle[n] = 1472;
        delay(20);
      }
    }
    else if (potVal >= 1372 && potVal <= 1572 ) {           
          angle[n] = 1472;
          }
      
    else if (potVal <= 1372 ) {
          angle[n] = potVal + 100;
          }
  
    else if (potVal >= 1572 ) {
          angle[n] = potVal - 100;
          }
  }
}

void moveServos() {
  for (byte n = 0; n < 4; n++) {
    servo[n].writeMicroseconds(angle[n]);
  }
}

Now im struggling with "kick off" code. it works , but not smooth as i want. Any suggestion about this?
