Save object or array in collection variable

Hi. Currently, I encountered a small problem.
I have a goal: to test counter(functionality that calculates numbers) in order to check this counter returns a number that falls under set range of low and high (±5% deviation)

Now, I have this piece of code:

    var allLists = JSON.parse(responseBody);
    
    var min = pm.variables.get("count"); // I separately extract min
    var max = pm.variables.get("count1"); // and max, but want to extract one variable with min and max;
    var low = parseInt(min)
    var high = parseInt(max);
    console.log("::MIN_VALIE: " + low + " | " + "::MAX_VALUE: " + high);
    
    pm.test("test count", function () {
        const value = allLists.data.count;
        console.log(":::::::::=> COUNTER: " + value);
        pm.expect(typeof value).to.eql('number');
        pm.expect(value > low && value < high).to.eql(true);
    });

It works ok, but I believe this code is bulky
In order to compare that value in the range of low and high I have to keep low and high number in separate collection variables, that out of desired 50 variables makes 100 variables and real mess.

Can I somehow keep one variable for low and high value in collection variables?

UPDATE: Right after posting came up with it:

var allLists = JSON.parse(responseBody);

var num = pm.variables.get("count").split(',');
var min = parseInt(num[0]);
var max = parseInt(num[1]);

console.log("::MIN_VALIE: " + min + " | " + "::MAX_VALUE: " + max);

pm.test("test count", function () {
    const value = allLists.data.count;
    console.log(":::::::::=> COUNTER: " + value);
    pm.expect(typeof value).to.eql('number');
    pm.expect(15 > min && 15 < max).to.eql(true);
});

it’s much better, but maybe exists better way
