The key to putting is consistency.
MyGolfSpy proved years ago, "looks" don't matter.
Just a moment...
Dave Stockton in "Unconscious Putting" gives this example. Sign your name on a piece of paper, then try to trace it slowly, while looking at it.
You need to be able to make an unconscious stroke, while maintaining the consistence of that stroke ... tempo & power (speed) & secondarily, direction.
