Oil weight question and cold weather

Additionally, after shutdown I also pull the dipstick of my IO-520 out a

Why would you want to catch the condensation and then keep it trapped at
the top of your engine? How about don't open the dipstick and let the
air circulate out of the engine normally thru the breather? This way
any water will drip on the floor.
