For whatever it is worth, the patch looks good to me. A minor nitpick would be to use a verb in the part: `cost when the parameter in (0, 1)` maybe: `cost when the parameter's value is in (0, 1)` or similar. Apart from that, I would suggest it that the patch could be moved to Waiting for Author state.
