I agree with Mike and Jordan's assessment, practice YOUR technique and have confidence in what YOU do.
As far as technique I use:
1. Deep breath before putting
2. Smile and act like I am at home practicing my putt with my daughter.
3. Direct all energy to one chain link, let it go, and don't worry about the results.
No wind or with the wind, I picture dropping it in the basket like a free throw.
Against wind, I remember what Jake told me, put a little spin on it.
One video that I like is Paul McBeth's video in his apartment. He taped the chains together and putted from about 30 ft. What I thought was interesting is how he hardly needs the chains or even the pole. He was just dropping them right into the basket.
