Attached is the datasheet for the driver I'm using. It's the LED100W-143-C0700-D model that I got.
It's linear down to 1V, and then goes non-linear to 0V ... the notes say: 0-10V dimmable version is not intended to dim below about 5% @ 0V

How is the sensitivity for dimming on the P model (PWM) Meanwell driver? I am running the D model of meanwell drivers (Analog 0-10) so it wouldn't work unless I swapped out all the drivers to PWM which I am willing to do if I gain some performance. I like the specs on the LLD model drivers.

i have no clue as i have never them, i only have experience with their non dimming drivers and the new LDD driver which has smooth dimming down to 0 with no issues.
LDD drivers can handle up to 52v, TR drivers dim to 5v and then have to be turned off.
although they max at 1amp, there is a membr on rc who is building a diy driver that max at 1400ma with the same pin out as the ldd drivers.

keith, stop talking and get to building.

I got started a bit last night. Sorted the LEDs (there are a LOT of them), worked out the wiring diagrams, etc. Hopefully I have time tonight to get them mounted & start on the soldering.
