how can i improve my fading text script to save performance ?

Hello, I'm trying to slowly fade a text with this script and slowly make it visible again. Unfortunately this script is not very elegant and a bit long. Can anyone help me to shorten or improve it?

while true do	
	script.Parent.TextTransparency = 0.05
	wait(0.2)
	script.Parent.TextTransparency = 0.1
	wait(0.2)
	script.Parent.TextTransparency = 0.15
	wait(0.2)
	script.Parent.TextTransparency = 0.2
	wait(0.2)
	script.Parent.TextTransparency = 0.25
	wait(0.3)
	script.Parent.TextTransparency = 0.3
	wait(0.2)
	script.Parent.TextTransparency = 0.35
	wait(0.2)
	script.Parent.TextTransparency = 0.4
	wait(0.2)
	script.Parent.TextTransparency = 0.45
	wait(0.2)
	script.Parent.TextTransparency = 0.5
	wait(0.2)
	script.Parent.TextTransparency = 0.5
	wait(0.2)
	script.Parent.TextTransparency = 0.45
	wait(0.2)
	script.Parent.TextTransparency = 0.4
	wait(0.2)
	script.Parent.TextTransparency = 0.35
	wait(0.2)
	script.Parent.TextTransparency = 0.3
	wait(0.2)
	script.Parent.TextTransparency = 0.25
	wait(0.2)
	script.Parent.TextTransparency = 0.2
	wait(0.2)
	script.Parent.TextTransparency = 0.15
	wait(0.2)
	script.Parent.TextTransparency = 0.1
	wait(0.2)
	script.Parent.TextTransparency = 0.05
	wait(0.2)
	script.Parent.TextTransparency = 0
	wait(0.2)
	print("finished")
	wait(0.2)
end
