Why does the speed value go up by a random number instead of 1?

local Player = game.Players.LocalPlayer
Player.Character.Humanoid.Running:Connect(function(speed)
	if speed > 0 then
		while wait(2) do
		Player.Stats.Speed.Value = Player.Stats.Speed.Value + 1
		end
	end
end)

local Player = game.Players.LocalPlayer
Player.Character.Humanoid.Running:Connect(function(speed)
    if speed > 0 then
        while wait(2) do
        Player.Stats.Speed.Value = Player.Stats.Speed.Value + math.random(1,100) -- set 100 to any amount you want
        end
    end
end)

Basically, math.random() chooses a random number from the first number to the second, so it would choose 1 through 100.
