My caster /
camber plates didn't need any hole hogging to work. They are UPR brand. They are great and stop the bushing flex at the top of the strut during cornering and maneuvers.
I'm a legit L1 technician. Master certified and over 20yrs experience. ( even though I'm still a dummy and learning all the time ).
True, they aren't needed to get the car into factory spec. unless the chassis is way off. When you start upgrading
suspension parts and brakes you need a more predictable top point for the strut. Driving like a normal car you'd probably never know the short comings of factory plates. Start driving hard and you'll feel the difference.
