Shot this drill again today, but this time I fired a few rounds slow fire to ascertain POI before I started. Turns out I need to hold the top of the sights between the top of the target and the top of the credit card to hit the credit card. Visually, it feels like I'm holding high on the target's forehead/hairline to drop the bullet into the eye sockets.
Same gear and par time as yesterday, but with 3-4 hits per run today. The tennis-ball sized hole is now in the credit card, and the people in the lanes on either side of me probably think that I have pretty severe anger management issues.
