Is it safe using BoolValues to determine whether data failed or not?

local DataStore = game:GetService("DataStoreService"):GetDataStore('NewStore')

local DefaultValue = 0

game.Players.PlayerAdded:Connect(function(Player)
	
	local Folder = Instance.new('Folder')
	Folder.Name = Player.UserId
	Folder.Parent = game.ServerStorage
	
	
	local Points_IntValue = Instance.new("IntValue")
	Points_IntValue.Name = 'Points'
	Points_IntValue.Parent = Folder
	
	local DataWasLoaded = Instance.new('BoolValue')
	DataWasLoaded.Name = 'DataWasLoaded'
	DataWasLoaded.Parent = Folder
	
	
	local S,E = pcall(function()
		return DataStore:GetAsync(Player.UserId)
	end)
	
	if S then
		
		if E and type(E) == 'number' then
			Points_IntValue.Value = E
			DataWasLoaded.Value = true -- Set Data loaded to true if it was succesfully loaded
		else
			
			Points_IntValue.Value = DefaultValue
			DataWasLoaded.Value = true -- Set Data loaded to true if it was succesfully loaded

		end
	
	else
		Points_IntValue:Destroy()
		DataWasLoaded.Value = false --Set Data loaded to false if it was failed

	end
	
	
end)

So Overall I just wanted to check if this was a good way to load data

Is there any improvements I can make?
