Bullseye Target Shooting

I"ve been doing some bullseye target shooting at the range recently. I put these out at 50 feet and shoot my Kimber Rimfire .22 at them, one-handed.

One of the guys at the range told me to use 1 slow-fire target and two rapid-fire targets. They look pretty similar, but the rings are a little differently valued.

You have as long as you want to shoot 10 rounds at the slow-fire target. Then for the first rapid-fire, you have 20 seconds each for 2 strings of 5 shots. On the second rapid-fire, you have 10 seconds each for 2 strings of 5 shots. (If I'm doing this wrong, someone tell me please)

Here are a couple of my recent targets:
