Some of the members in the forums talk about slight 'off-dinging', and I've read about it after one of the popular 'long timers' linked the putting tip thread in the forum.
" Aim your putt with a little less break and miss early or late. I don't do this all the time, but 3-15 footers I do on almost every one. The amount you want to miss depends on the forgiveness of your putter. Also be aware that you'll want to add on more pace depending on the severity you miss early or late. It will take off power when you miss the ding."

The another great player commented on how Tekoma was 'off dinging' and what the results were.
"none of those putts would have fell if it were not for missing ding which is a bonus using rossa putter cause IMO it was built just for that. Maybe a little reasoning to why you missed the ding by how much you did would benefit players more."
I sometimes use the off ding method, and that's esp. why I'm using the TM Spider. But I usually make the judgment on how much I need to miss just before I pull the putter back (then the dots stop moving etc) and I don't make that decision after I've adjusted the power.
I can understand people have their preferences, I just work with what my browser gives me. (and actually I don't think my browser ever had the dots moving while I was in the middle of a swing)
