Then I found this:
“The default on the Focusrite is the same as the SSL.

dBu PPM Meter Reference -20dBFS
Vu Meter Reference -10dBFS”
Which seems to match the wonkiness I’m seeing in the pictures but doesn’t make much sense to me. What consoles are calibrated so that 0dbVU = +10dbu?!? But I guess that’s what they’ve decided to do. Does this help answer your question? I guess basically if you’re used to VU meters calibrated to 0VU = -18dbFS, you should look at the dbu meter and shoot for +2, or else shoot for -8 on the VU meter. Or something...
Or change the internal calibration?

I could also use a separate metering plugin, either pre or post BX.
