Can i use String Values for Stats?

I want to make a Incremental game with Runes. Is it better to use Encoded StringValues than Normal StringValues with Eternity/Omega Num? bcs for 5 stats i would need 5 StringValues and with that i would need only 1. So my question is: “Is it bad practice to use that”? Because i need to encode and decode it.

Example:

local rs = game:GetService("ReplicatedStorage")
local on = require(rs.Shared.game.libs.OmegaNum)
local httpService = game:GetService("HttpService")


return {
	Stats = function(player: Player) 

		local Stats = Instance.new("StringValue", player)
		Stats.Name = "Stats"

		local values = {
			["Cash"] = {
				["Name"] = "Cash",
				["Value"] = on.toString(on.add(0, 0)),
				["Unlocked"] = true,
			},

			["RobuxSpend"] = {
				["Name"] = "RobuxSpend",
				["Value"] = on.toString(on.add(0, 0)),
				["Unlocked"] = true,
			},

			["Playtime"] = {
				["Name"] = "Playtime",
				["Value"] = on.toString(on.add(0, 0)),
				["Unlocked"] = true,
			},

			["RuneLuck"] = {
				["Name"] = "RuneLuck",
				["Value"] = on.toString(on.add(1, 0)),
				["Unlocked"] = true,
			},

			["RuneBulk"] = {
				["Name"] = "RuneBulk",
				["Value"] = on.toString(on.add(1, 0)),
				["Unlocked"] = true,
			},

			["RuneSpeed"] = {
				["Name"] = "RuneSpeed",
				["Value"] = on.toString(on.add(1, 0)),
				["Unlocked"] = true,
			},
		}
		Stats.Value = httpService:JSONEncode(values)
	end
}

For an incremental game, where you might have big numbers but not super frequent updates for every stat, your encoded StringValue approach is fine just make sure to write utility functions so you’re not constantly retyping JSONDecode/JSONEncode.
If your game starts lagging from massive JSON updates every frame, you can switch to hybrid some higher frequency stats as separate values, everything else in JSON.
