Looks to 2 to 3x speed (close anyway) and it doesn’t take a lot of trickery to keep this guy going.
On his setups @ 1:40 I count 2 T slot key blocks parallel to the cross travel (usually hardened with a close fitting key for the T slot and sometimes, like his, are tapped for adjustable stop screws).
At 2:14-18 a slip block for referencing the part parallel over the front of the table finger close (close enough for flame cut part anyway, here it doesn’t matter).
At 2:49 he’s got the key slot blocks back on & you can clearly see the key down in the T slots. It’s also clear the T slots haven’t had a lot of banging done to them...
2 clamp straps down on the table for a parallel fence to the spindle at 3:18 (using a clock indicator here).
At 3:22 you see 2 big woodruff keys underneath his clamp straps (this is very smart with irregular parts & you don’t have spherical washers).
At 3:38 the part is up on some parallels and against 2 small (narrow) knees. Because they can be anywhere but need to be the same from the slot to front face they (likely) are keyed to the T slots, or (if not keyed) set from the front of the table using a story pole.
At 3:45 he has the T slots parallel to the spindle with a strap parallel to the cross way and a big key snugged in the slot for a small right angle stop.
His particular machine has a rotating top table. Some have locks for 0-90-180-270, but for normal stuff all are set with the slot either parallel to the spindle & bed ways, or parallel to the cross way travel. This is the only time an HBM driver will do something similar to miller trying to make 2 vices the same on a table using machine travels (back & forth a few times with an indicator).
Since you really can’t trust a partially machined weldment and prior machining “still being right”. At 6:35 he’s dinking the part back & forth (rare)… At 6:46 he finds the part side but does not find the bore height (already knows the spindle height to table).
At 7:58 he’s making sure the face down is OK (not warped) and shimming before clamping (square on the table works pretty well too if you like).
At 8:42 he’s got 2 long keys stuck in the front slot… After that, well they’re just chain links.
I've said it before, I'd hate to battle the guy,
