I can't see anything wrong with what ShootingTheBull410 does.
He uses IWBA-specification 16oz per square yard, heavy denim, his blocks are BB calibrated and temperature controlled.
I consider his results valid.
The clear gel tests are more of a gateway test - if it fails in the clear gel he doesn't waste time and money with ordnance gel and 4 layers of denim.
Another non-JHP that performs well is the Lehigh XP Xtreme Penetrator and it doesn't shoot clean out the back of assailants.
