Quarter Acre, right at 54 seconds in too.
With out perch I have out first shoot only 2 seconds. Then wait 10 minutes and do a 4 sec shot then another 10 minutes a 4 sec shot.
I find the first shot brings in the minnows and small perch. The feeding triggers the big boys to show up and that's when we shoot the 4 sec shot. Works well little waste and everyone gets some.
