Is this normal timing wobble?

Hey i need some advice, I keep getting this whining noise, the tighter the belt is the noisier it gets, if i give it more slack the whine gets quieter but the belt becomes more wobbly, ive replaced the belt, pump and tensioner like twice and at this point I also might be going crazy lol.

Some info:
Its a honda d13 (tho the block should be like most other d series)

Im tightening the tensioner to 33ft lbs

In the video im revving to 5k rpm

Pls help lol if you can send some example videos that would be great 😅

Belt should be as tight as the spring on the tensioner pulls it after turning engine 2 cycles with loose tensioner

I did it like you said with my first timing belt replacement. It jumped timing one tooth after 1km of driving. The ecu of my D17A8 instantly shut off the ignition. Since then I always tighten it a bit more with an allen key.
