Sampling Multiple Myoware EMG sensonr signals

I recently purchased 2 Myoware Muscle sensors to work on an EMG based project. I’m trying to read 2 analog signals simultaneously using the arduino board at 2KHz sampling frequency each, over a window of 0.1 seconds and calculating the energy ( log(RMS)) of that signal over that window and looping this for 1 to 2 minutes.
Im unsure of the data i’m getting. Could it be because we cannot analog read 2 different signals in arduino simultaneously at that frequency or because of the baud rate?. Could someone review my arduino code if possible. I have attached the picture of what i’m trying to do and my code.

My code:

int sensor1Pin = 0;
int sensor2Pin = A2;// sensor 1
int sensor3Pin = A3;// sensor 2

int v=200; //number of samples in a window of (0.1 second)
float sensorVal[] = {0,0,0};
 int count=0;
 
void setup(){
Serial.begin(9600); //This line tells the Serial port to begin communicating at 9600 bauds
}

//
void loop(){
//read each sensor value. We are assuming analog values. Customize as nessary to read all of your sensor values into the array. Remember to replace "sensor1Pin" and "sensor2Pin" with your actual pin names from above!
//sensorVal[0] = analogRead(sensor1Pin);
//

if(count==600) // loop control for 1 minute of measurement
while(1)
;
count++;
/*If you are reading digital values, use digitalRead() instead. Here's an example:
sensorVal[0] = digitalRead(sensor1Pin);
*/
 
  int counter=0;
  double rms1=0.0,rms2=0.0, sum1=0.0,sum2=0.0, val1=0.0,val2=0.0,log_rms1=0.0,log_rms2=0.0;
  
 unsigned long elapsed;
 unsigned long startTime=micros();
  while (counter<v)
  {
     
      sensorVal[1] = analogRead(sensor2Pin)*5 /1024;
      
      sum1 = sum1 + sensorVal[1]*sensorVal[1];

      delay(0.25); 
      
      sensorVal[2] = analogRead(sensor3Pin)*
      5/1024  ;
      sum2 = sum2 + sensorVal[2]*sensorVal[2];
    //Serial.print(counter);
    //Serial.print("\t");  
    
    delay(0.25); //total delay of .5 millisecond of 2000 samples a second 
    counter=counter + 1;
    
  }
  unsigned long currentTime=micros();
  elapsed=currentTime-startTime;
  Serial.print(elapsed);
  Serial.print("\t");
  log_rms1=0.5*(log(sum1)-log(v));
  log_rms2=0.5*(log(sum2)-log(v));
  val1=sum1/v;
  val2=sum2/v;
  rms1=sqrt(val1);
  rms2=sqrt(val2);
  Serial.print(rms1);
  Serial.print(",");
  Serial.print(rms2);
  Serial.print(",");
  Serial.print(log_rms1);
  Serial.print(",");
  Serial.print(log_rms2);

Hi, I know this post a little bit old. But I have a question since I did the same project, how do you know you sampling at 2kHz?
