We tested the Touch putter to see if an off center strike with the robot 0.5 inches in either direction from the sweet spot would affect distance and line. Our putter performed very well. It held it's line as expected and did not lose any distance on heel struck putts. The toe struck putts lost a insignificant amounts of distance on some tests but had others that rolled out the same distance, suggesting distance lost is due to other factors such as inconsistencies in the carpet and possible striking on a corner of a dimple.
We plan to do more testing and release the results in a later blog update.
