Myservo detach ?

I have a servo ( 4 turns type ) that jitters at position and I cant seem to get it to stop jittering , I want to DETACH the servo when it gets to position to stop the jitter , I tried using myservo.detach() on pin 9 ( so it should be myservo.detach(9) right ? ) If I put the 9 in there it will not compile ?
how should this code be written ? I looked up some other discussions about this but could not get it to work.

//Nanometer tech regulator 0-25 psi rev F

#include <Servo.h>

Servo myservo;  // create servo object to control a servo
int potpin = 0;  // analog pin used to connect the potentiometer
double val;    // variable to read the value from the analog pin

double mapf(double val, double in_min, double in_max, double out_min, double out_max) {
	return (val - in_min) * (out_max - out_min) / (in_max - in_min) + out_min;
}

void setup() {
  myservo.attach(9);  // attaches the servo on pin 9 to the servo object
Serial.begin(9600);
}

void loop() {
  val = analogRead(potpin);   // reads the value of the potentiometer (value between 0 and 1023)
  val = mapf((double)val, 0.0, 1023.0, 1000.0, 2080.0);// scale it to use it with the servo (value between 0 and 180)
  myservo.writeMicroseconds(val);     // sets the servo position according to the scaled value
  delay(15);                           // waits for the servo to get there
  int sensorValue2 = analogRead(A0);
  // Convert the analog reading (which goes from 0 - 1023) to a voltage (0 - 5V):
  float voltage2 = sensorValue2 * (5.0 / 1023.0);
  Serial.println(voltage2); 
  Serial.println("Volts");
   Serial.println(val); 
  delay(450);  
   
}

Delta_G:
Don't be afraid to read the reference:

Servo - Arduino Reference

Does it say that detach needs any pin numbers or other arguments?

Ya got that part , how about the rest of the post ? the servo does not seem to detach when I add it to the LOOP , it just jitters

end of loop code below :

Serial.println(val);
delay(450);
{
myservo.detach();
}

Are you sure the pot value is not jittering? Write microseconds() takes an integer, you're sending it a float.
