Belt tension

[944TurboS]

Replacing a water pump on my 951.
Just bought the cam belt tool from Tom in lieu of the P9201.
Now I just need a foolproof way to set the tension on the other 3 belts as newbie.
Balance shaft belt apparently very floppy with 270 degree (?) twist. Any other, more quantitative P9210-less way of going about it?
And what about the power steering belt and the AC / Alternator belt? Could I use a Kricket tool instead of the 90 degree twist method?
Going through the forums, many different opinions…

It's time-consuming, but you can reliably set the balance shaft by making it just loose enough that it stops whining. At the high end of the factory spec, 4.0, it will make a slight whine. By 3.5, the mid-point of the spec, the whine is all gone. I've been meaning to do a tool for the balance shaft -- need to get on that! For the p.s. and a/c belts, I'd just use your best judgement. When tightened to spec with the 9201, they are both super tight. So much so, that I don't use the 9201 on those belts and instead tighten them until they feel like normal fan belts.

What would that tool look like? Similar to the cam belt one?

I'll start a gofundme for this! I have the arnworx tool and while I am confident in the quality of the installation I've never been able to get rid of the whine.

Please help me Tom!

Ok, I'll put it at the top-ish of my list. If it is whining, it's tight. The scale is 3.5 +/- .5 on the 9201. If you set it to 4.0, you will have a whine -- not super loud, but it will be there. By 3.5 it seems to stop whining, or at least that's been my experience.
