Very few are going to leave 5 stars or Very Reasonable on anything.
How can you say this? It's obvious that even with your not so stellar stars about half of your buyers give you 5's.
There are lots of Powersellers who will get the discount, eBay has stated that currently 75% would qualify for one or the other discount level. With the exception of the shipping stars there are tons of Powersellers with 4.8/4.9 ratings and many of these are very close to the 4.8 across the board need for the maximum discount.
Currently a few hits to your ratings can have a long lasting impact. The new 30 day calculations will help to alleviate this.
