Dunno about the left wing low malarcy....but I was taught 30 ft check and flare...20 feet close thrust levers....and gently does it...
Then when your really good.....drop everything by 10 feet..i.e check flare at 20 feet..close thrust levers at 10 feet. Dont forget to fly the nose wheel onto the runway..otherwise she will bite..with a thump!
