China does the same. They have one target plate (220 mm) for their 105 mm, 120 mm and 125 mm APFSDS rounds - they just change the slope for different rounds.

This clears up some of the mystery of why the data for L23 seems to vary so much. Thanks for that.

That's very weird. You can't determine penetration depth by simulating semi-infinite plate by just increasing the angle. The data you get from testing the same plate at different angles will be different for the same impact velocity.
If it is 'it's path of round inside inclined target' then that is going to not be especially inaccurate. The lower efficiency of angled plate vs APFSDS at non deflecting angles is mostly from a shorter channel due to dig in, so it will not show upward biased results if you measure the channel length, as it will if you use the LOS @ 90 deg.
