Belt Twist at home position

Hi folks,

After completing the MK4S-to-Core One Plus conversion and reaching the (somewhat confusing) belt tensioning stage of the setup, I noticed that the lower belt has a visible twist when the extruder is at its home position.

I've already completed a number of prints on the machine, and there don't appear to be any obvious issues as a result. However, I wanted to check with the community to see whether anyone else has noticed this or experienced any problems related to it.

The twist is fairly minor—I'd estimate about a 30° corkscrew twist in the belt. It straightens out as the extruder moves toward the center of the X/Y travel. My assumption is that the belt may have developed some "memory" from the way it was packaged, but visually it doesn't seem to be causing any issues.

Has anyone seen this before? Do you think it's worth ordering a replacement belt, or is a small amount of twist like this considered normal?

Thanks for your time and any advice you can provide.
