How Would I make my NPC'S Movement smooth in this script?

I'm currently working on making my own pathfinding enemy script and so far everything has worked. However the NPC's movement is jittery and it seems to stop and move very often. I feel this is to do with my loop calling the function every .03 seconds. All I'd like is it to not do this, but for it to be able to seamlessly switch between targets and for it not to act so jittery. Help appreciated.

Code

local PathfindingService = game:GetService("PathfindingService")
local Humanoid = script.Parent.Humanoid
local HumanoidRootPart = script.Parent.HumanoidRootPart
local MaxDistance = 200
function FindClosestTarget(MaxDist, TableOfCurrentPlayers)
	local Target
	local SmallestDistance = MaxDist
	local PlayerWithSmallerDistance
	for _, player in pairs(TableOfCurrentPlayers) do
		local distance = player:DistanceFromCharacter(HumanoidRootPart.Position)
		if distance < SmallestDistance then
			SmallestDistance = distance
			PlayerWithSmallerDistance = player
		end
	end
	Target = PlayerWithSmallerDistance
	if Target ~= nil then  --Check if it isn't nil
		print(Target.Name) 
	end
	return Target
end

function FindAndMoveToTargetPos()
	local TargetToMoveTo = FindClosestTarget(MaxDistance, game.Players:GetPlayers())
	local TargetChar = TargetToMoveTo.Character
	if TargetChar then
		local Target_HRP = TargetChar:WaitForChild("HumanoidRootPart",5)
		local path = PathfindingService:CreatePath()
		path:ComputeAsync(HumanoidRootPart.Position, Target_HRP.Position) 
		local waypoint = path:GetWaypoints()
		for i, waypoint in pairs(waypoint) do
			if waypoint.Action == Enum.PathWaypointAction.Jump then 
				Humanoid.ChangeState(Enum.HumanoidStateType.Jumping)
			end
			Humanoid:MoveTo(waypoint.Position) 
			Humanoid.MoveToFinished:Wait() 
		end
	end
	return TargetToMoveTo
end

while wait() do
	local Closest = FindClosestTarget(MaxDistance,game.Players:GetPlayers())
	local CurrentTarget = FindAndMoveToTargetPos()
	if Closest ~= CurrentTarget then
		FindAndMoveToTargetPos()
	end
end
