Coasterhunk has been posting a lot of poorly explained rates lately.

This ride was underbanked and very rough. You obviously used the tool on this ride and should have hand banked some of your tunrarounds. The vertical G's were also very high.

This ride was fun, but wasn't all that origonal. The layout was smooth and the spped was OK, but it really slowed at the end. OK ride.
Those are just two examples. Both scores were well below averages for the rides.
