Yeah I think there have been a couple of discussions about this since the app came out. The tough part for me is I can see the rationale either way - getting the same number of points with fewer tiles placed seems like an achievement, but so does placing more tiles.
To keep it simple (one of the guiding principles of the ladder,) I suggest we adhere to the results as listed by the app for every game we play. Happy to put it to a vote if it’s a big enough source of contention.
