My rotation isn't working smoothly, how do i fix it? (now with code block)

How do i make this go smoother without changing the dely between each 'frame'? My code

~~~~~~~~~~~~~~~~~ local model = script.Parent local mainPart = model.Center -- the "Origin" of rotation. --Rotation values (in degrees): ** local rotX = 5 local rotY = 0 local rotZ = 0 local delay = 0.9 -- delay between each "Frame" local mTable = {} local offsetTable = {} function getListOfParts(inst) for i, v in pairs(inst:GetChildren()) do if v:isA("BasePart") then table.insert(mTable, v) else getListOfParts(v) end end end getListOfParts(model) for i, v in pairs(mTable) do offsetTable[i] = mainPart.CFrame:toObjectSpace(mTable[i].CFrame) end while wait(delay) do mainPart.CFrame = mainPart.CFrame * CFrame.Angles(math.rad(rotX), math.rad(rotY), math.rad(rotZ)) for i, v in pairs(mTable) do v.CFrame = mainPart.CFrame * offsetTable[i] end end`
