Do CoreXY belts need to be of equal tension? (no replies)

Hi guysI have a bit of a dilemma here: in a corexy setup, do I have to make sure belts have the same tension on both sides?
As far as I can tell, having them adjusted differently can help squaring the top -which is notoriously difficult to square as one can't install cross bracing in there- and also (maybe) can be used for other artifacts in prints (oval circles,etc).

Please let me know your experience with proper tension in the belts.

Note: I have a design that does simultaneous tensioning of both belts but it has been brought to my attention that it might not be the best solution.

Thanks.
