Max Number of Vus not matching with number of pods

Hi all,
I am using k6 oss via operator in k8. I initilize the test with parallelism 4 and emitting metrics to influx. Here is my options while setting up load test :

export const options = {
  scenarios: {
    ramping_arrival_rate: {
      executor: 'ramping-arrival-rate',
      startRate: 25, // Starting at 100 RPS
      timeUnit: '1s', // RPS will be calculated per second
      preAllocatedVUs: 200, // Preallocate 50 VUs
      maxVUs: 3500, // Maximum number of VUs
      stages: [
        { target: 125, duration: '3m' },   // Ramp up to 500 RPS in 3 minutes
        { target: 250, duration: '1m' },  // Ramp up to 1000 RPS in the next 2 minutes
        { target: 375, duration: '2m' },  // Ramp up to 1500 RPS in the next 2 minutes
        { target: 500, duration: '3m' },  // Finally ramp up to 2000 RPS in 3 minutes
        { target: 500, duration: '5m' },  // Maintain 2000 RPS for 5 minutes
        { target: 0, duration: '2m' },     // Ramp down to 0 RPS over 2 minutes
      ],
    },
  },
};

env: 
                - name: K6_OUT
                  value: influxdb=http://admin:admin@<influx>:8086/load_test_results

when i run my test I see 4 pods running but what I want to know is that when I query vus measurement shouldnt I get sum of all vus as 4*3500
ie

SELECT sum("value") FROM "rp_15d"."vus" WHERE  time >= now() - 24h and time <= now() GROUP BY time(1s) fill(none)

I am getting 3500 only what am I missing here ?

also on querying

select * from vus order by time desc limit 5;

I get

time                instance_id job_name    testid                  value

what is the value signifying here ?
