Hi Neil, this is a great question and one that the team is aware of. On Arccos, if you mark a putt as a chip, ie when you use a putter from off the green, it automatically defaults the lie to rough and a user cannot change it. This therefore feeds into Clippd as an ARG shot played from the rough, which will impact your ARG Shot Quality (it will slightly increase because rough is deemed to be a trickier lie than fairway).
We have it in the pipeline to correct this by assuming any putter marked as a chip in Arccos was played from the fairway, because we know 99.9% of putts from off the green are played from the fairway or fringe. When this fix is done we will be sure to let you know.
In the meantime, I would suggest keep doing what you are doing because if you enter it as anything else (such as leaving it as a putt) it will have an effect on both your APP Shot Quality and your PUTT Shot Quality. By continuing to do what you do now, the impact will be minimal impact until we release the change.
Hope this helps.
