I've been slaying them when I bait properly. That's 4-8 every time and occasionally a big day of 9 or even 10.
Here's what I do. I'm shooting from inside down into a privacy fenced garden. It is perhaps 75' x 27'. I have two thistle socks, always filled, nearer to the house. Thus, I have lots of finches all the time, all day, unless there's a cat there or I'm too close. I've also got doves and juncos and song sparrows under the thistle socks. Then, further out, toward the last 10-15 feet of garden, I have my sunflower seed feeder. This has all the usual suspects on it and under it. It is always filled. I also have a suet cage hanging next to it. Then, I get down to brass tacks.
Just 10-15' to the east and slightly closer to the house I have my starling bait area. It's a dispersed area, maybe 10-12' oblong. When I bait, I use suet and bread and/or cat food right on the ground (I've not had to use much catfood), and any greasy or fatty left overs, like Steak bones and fat, or lamb shoulder if and as available (only during winter,thank you).
I think that the key to getting more birds in is that I broadcast some small piles of sunflower seeds in the area.. The starlings aren't interested of course. The Doves and cardinals are. So, the starlings see all these other excited birds eating food right next to their suet and bread. Furthermore, after I kill a starling, the other birds don't budge, they keep eating away...again, right in their food. And the starlings seem to freak out if they are watching the feed from the trees and a flock of doves comes in on it. Their greed instinct kicks in and they fly to the bait.
Essentially, I'm using live, non-starlings as decoys/shills for the starlings, in addition to providing lots of fat and bread spread out on the ground. I usually only collect birds a couple times a day, but they still come in (sometimes more nervously).
Hope that helps.
