Hi! The behavior you have described does not seem to be intended. Only the curation rewards (25% to 0% scaling linearly for first 15 mins) is returned, so the author should still get 75%.

It says the "early voting penalty" is returned, which is the 25% at 0 mins, so the author should still be getting 75% (at all times instead of the old 100% to 75% scale) and curators have the same scale as before (0% to 25%).

I hope this is correct and makes sense!
