I get max 450 distance readings per second in fastest mode 2, and max 250 in mode 0 (better accuracy).
The sampling speed decreases with distance (the closer the lower), at very short distances it is about 70 readings/s, not sure why.
So at about 450 readings/s we get 45 readings per revolution at 10Hz, that is pretty low angular resolution - 8° (at 10m we have pretty big gaps), so two or more LIDAR sensors may help a bit or reducing the rotation speed.
I did some tests with the LIDAR Light 3, I posted the code here:

See here how is the laser spot and why it is so big, 8 cm at 10m: https://www.robotshop.com/forum/angular-resolution-and-nominal-range-of-lidar-lite-t12456

Accuracy/consistency is not that great especially at short distances it varies even 30cm at 30cm distance, same as in the reviews:
